Note 1. THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The Company

SunPower Corporation (together with its subsidiaries, the "Company" or "SunPower") is a vertically integrated solar products and solutions company that designs, manufactures and delivers high-performance solar systems worldwide, serving as a one-stop shop for residential, commercial, and utility-scale power plant customers. SunPower Corporation is a majority owned subsidiary of Total Energies Nouvelles Activités USA("Total"), a subsidiary of Total S.A. ("Total S.A.") (see Note 2).

Basis of Presentation and Preparation

Principles of Consolidation

The consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America ("United States" or "U.S.") and include the accounts of the Company, all of its subsidiaries and special purpose entities, as appropriate under consolidation accounting guidelines. Intercompany transactions and balances have been eliminated in consolidation. The assets of the special purpose entities that the Company sets up related to project financing for customers are not designed to be available to service the general liabilities and obligations of the Company in certain circumstances.

Reclassifications

Certain prior period balances have been reclassified to conform to the current period presentation in the Company's consolidated financial statements and the accompanying notes. Such reclassifications had no effect on previously reported results of operations or accumulated deficit.

Fiscal Years

The Company has a 52-to-53-week fiscal year that ends on the Sunday closest to December 31. Accordingly, every fifth or sixth year will be a 53-week fiscal year. Both fiscal 2014 and 2013 are 52-week fiscal years. The third quarter of fiscal 2014 ended on September 28, 2014, while the third quarter of fiscal 2013 ended on September 29, 2013. The third quarters of fiscal 2014 and fiscal 2013 were both 13-week quarters.

Management Estimates

The preparation of the consolidated financial statements in conformity with U.S. generally accepted accounting principles ("U.S. GAAP") requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Significant estimates in these consolidated financial statements include percentage-of-completion for construction projects; allowances for doubtful accounts receivable and sales returns; inventory and project asset write-downs; stock-based compensation; estimates for future cash flows and economic useful lives of property, plant and equipment and other long-term assets; the fair value and residual value of leased solar power systems; fair value of financial instruments; valuation of certain accrued liabilities such as accrued warranty; and income taxes and tax valuation allowances. Actual results could materially differ from those estimates.

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board ("FASB") issued a new revenue recognition standard based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. The new revenue recognition standard becomes effective for the Company in the first quarter of fiscal 2017 and is to be applied retrospectively using one of two prescribed methods. The Company is evaluating the application method and impact on its consolidated financial statements and disclosures.

In July 2013, the FASB amended its guidance related to the presentation of unrecognized tax benefits. The amended guidance specifies when an unrecognized tax benefit or a portion of an unrecognized tax benefit should be presented as a liability versus an offset against a deferred tax asset when a net operating loss carryforward, a similar tax loss or tax credit carryforward exists. The amendment became effective for the Company in the first quarter of fiscal 2014 and did not have a material impact on its consolidated financial statements.

8

In March 2013, the FASB and International Accounting Standards Board ("IASB") issued common disclosure requirements that are intended to enhance comparability between financial statements prepared in accordance with U.S. GAAP and those prepared in accordance with International Financial Reporting Standards ("IFRS"). This new guidance is applicable to companies that have financial instruments or derivatives that are either offset in the balance sheet (presented on a net basis) or subject to an enforceable master netting arrangement or similar arrangement. The requirement does not change the existing offsetting eligibility criteria or the permitted balance sheet presentation for those instruments that meet the eligibility criteria. However, once this disclosure requirement becomes effective, companies will also be required to disclose information about financial instruments and derivatives instruments that have been offset and related arrangements and to provide both net (offset amounts) and gross information in the notes to the financial statements for relevant assets and liabilities that are offset. The disclosure requirement became effective retrospectively in the first quarter of the Company's fiscal year 2014 and did not have a material impact on the Company's consolidated financial statements as the requirement is disclosure-based only.

In March 2013, the FASB amended its guidance related to foreign currency matters requiring the release of the cumulative translation adjustment into net income when an entity ceases to have a controlling financial interest in a subsidiary or a group of assets within a foreign entity. The amendment became effective for the Company in the first quarter of fiscal 2014 and did not have a material impact on its consolidated financial statements.

Other than as described above, there has been no issued accounting guidance not yet adopted by the Company that it believes is material or potentially material to its consolidated financial statements.

Note 2. TRANSACTIONS WITH TOTAL AND TOTAL S.A.

In June 2011, Total completed a cash tender offer to acquire 60% of the Company's then outstanding shares of common stock at a price of $23.25 per share, for a total cost of approximately $1.4 billion. In December 2011, the Company entered into a Private Placement Agreement with Total, under which Total purchased, and the Company issued and sold, 18.6 million shares of the Company's common stock for a purchase price of $8.80 per share, thereby increasing Total's ownership to approximately 66% of the Company's outstanding common stock as of that date.

Credit Support Agreement

In fiscal 2011, the Company and Total S.A. entered into a Credit Support Agreement (the "Credit Support Agreement") under which Total S.A. agreed to enter into one or more guarantee agreements (each a "Guaranty") with banks providing letter of credit facilities to the Company. Total S.A. will guarantee the Company's obligation to reimburse the applicable issuing bank a draw on a letter of credit and pay interest thereon in accordance with the letter of credit facility between such bank and the Company. Under the Credit Support Agreement, the Company may also request that Total S.A. provide a Guaranty in support of the Company's payment obligations with respect to a letter of credit facility. The Company is required to pay Total S.A. a guarantee fee for each letter of credit that is the subject of a Guaranty under the Credit Support Agreement and was outstanding for all or part of the preceding calendar quarter.

The Credit Support Agreement will terminate following the fifth anniversary of the CSA Effective Date, after the later of the payment in full of all obligations thereunder and the termination or expiration of each Guaranty provided thereunder.

Affiliation Agreement

The Company and Total have entered into an Affiliation Agreement that governs the relationship between Total and the Company (the "Affiliation Agreement"). Until the expiration of a standstill period (the "Standstill Period"), and subject to certain exceptions, Total, Total S.A., any of their respective affiliates and certain other related parties (the "Total Group") may not effect, seek, or enter into discussions with any third-party regarding any transaction that would result in the Total Group beneficially owning shares of the Company in excess of certain thresholds, or request the Company or the Company's independent directors, officers or employees, to amend or waive any of the standstill restrictions applicable to the Total Group.

The Affiliation Agreement imposes certain limitations on the Total Group's ability to seek to effect a tender offer or merger to acquire 100% of the outstanding voting power of the Company and imposes certain limitations on the Total Group's ability to transfer 40% or more of outstanding shares or voting power of the Company to a single person or group that is not a direct or indirect subsidiary of Total S.A. During the Standstill Period, no member of the Total Group may, among other things, solicit proxies or become a participant in an election contest relating to the election of directors to the Company's Board of Directors.

9

The Affiliation Agreement provides Total with the right to maintain its percentage ownership in connection with any new securities issued by the Company, and Total may also purchase shares on the open market or in private transactions with disinterested stockholders, subject in each case to certain restrictions.

The Affiliation Agreement also imposes certain restrictions with respect to the Company's and its Board of Directors' ability to take certain actions, including specifying certain actions that require approval by the directors other than the directors appointed by Total and other actions that require stockholder approval by Total.

Research & Collaboration Agreement

Total and the Company have entered into a Research & Collaboration Agreement (the "R&D Agreement") that establishes a framework under which the parties engage in long-term research and development collaboration ("R&D Collaboration"). The R&D Collaboration encompasses a number of different projects, with a focus on advancing the Company's technology position in the crystalline silicon domain, as well as ensuring the Company's industrial competitiveness. The R&D Agreement enables a joint committee to identify, plan and manage the R&D Collaboration.

Liquidity Support Agreement with Total S.A.

The Company was party to an agreement with a customer to construct the California Valley Solar Ranch, a solar park. Part of the debt financing necessary for the customer to pay for the construction of this solar park was provided by the Federal Financing Bank in reliance on a guarantee of repayment provided by the Department of Energy (the "DOE") under a loan guarantee program. In February 2012, the Company entered into a Liquidity Support Agreement with Total S.A. and the DOE, and a series of related agreements with Total S.A. and Total, under which Total S.A. agreed to provide the Company, or cause to be provided, additional liquidity under certain circumstances to a maximum amount of $600.0 million ("Liquidity Support Facility").  The Liquidity Support Facility was available until the completion of the solar park, which was completed in accordance with the terms of the relevant agreement in March 2014. Upon completion, the Liquidity Support Agreement was terminated. There were no outstanding guarantees or debt under the facility upon termination.

Compensation and Funding Agreement

In February 2012, the Company entered into a Compensation and Funding Agreement (the "Compensation and Funding Agreement") with Total S.A. which established the parameters for the terms of liquidity injections that may be required to be provided by Total S.A. to the Company from time to time. During the term of the Compensation and Funding Agreement, the Company is required to pay Total S.A. a guarantee fee in an amount equal to 2.75% per annum of the average amount of the Company's indebtedness that is guaranteed by Total S.A. pursuant to any guaranty issued in accordance with the terms of the Compensation and Funding Agreement during such quarter. Any payment obligations of the Company to Total S.A. under the Compensation and Funding Agreement that are not paid when due accrue interest until paid in full at a rate equal to 6-month U.S. LIBOR as in effect from time to time plus 5.00% per annum.

Upfront Warrant

In February 2012, the Company issued a warrant (the "Upfront Warrant") to Total S.A. to purchase 9,531,677 shares of the Company's common stock with an exercise price of $7.8685, subject to adjustment for customary anti-dilution and other events. The Upfront Warrant, governed by the Private Placement Agreement and the Compensation and Funding Agreement, is exercisable at any time for seven years after its issuance, provided that, so long as at least $25.0 million in aggregate of the Company's convertible debt remains outstanding, such exercise will not cause "any person," including Total S.A., to, directly or indirectly, including through one or more wholly-owned subsidiaries, become the "beneficial owner" (as such terms are defined in Rule 13d-3 and Rule 13d-5 under the Securities and Exchange Act of 1934, as amended), of more than 74.99% of the voting power of the Company's common stock at such time, a circumstance which would trigger the repurchase or conversion of the Company's existing convertible debt.

0.75% Debentures Due 2018

In May 2013, the Company issued $300.0 million in principal amount of its 0.75% senior convertible debentures due 2018 (the "0.75% debentures due 2018"). $200.0 million in aggregate principal amount of the 0.75% debentures due 2018 were acquired by Total. The 0.75% debentures due 2018 are convertible into shares of the Company's common stock at any time based on an initial conversion price equal to $24.95 per share, which provides Total the right to acquire up to 8,017,420 shares of the Company's common stock. The applicable conversion rate may adjust in certain circumstances, including a fundamental change, as described in the indenture governing the 0.75% debentures due 2018 (see Note 9).

10

0.875% Debentures Due 2021

In June 2014, the Company issued $400.0 million in principal amount of its 0.875% senior convertible debentures due 2021 (the "0.875% debentures due 2021"). An aggregate principal amount of $250.0 million of the 0.875% debentures due 2021 were acquired by Total. The 0.875% debentures due 2021 are convertible into shares of the Company's common stock at any time based on an initial conversion price equal to $48.76 per share, which provides Total the right to acquire up to 5,126,775 shares of the Company's common stock. The applicable conversion rate may adjust in certain circumstances, including a fundamental change, as described in the indenture governing the 0.875% debentures due 2021 (see Note 9).

Joint Projects with Total and its Affiliates:

The Company enters into various engineering, procurement and construction ("EPC") and operations and maintenance ("O&M") agreements relating to solar projects, including EPC and O&M services agreements relating to projects owned or partially owned by Total and its affiliates. As of September 28, 2014, the Company had $34.3 million of "Costs and estimated earnings in excess of billings" and $38.8 million of "Accounts receivable, net" on its Consolidated Balance Sheets related to projects in which Total and its affiliates have a direct or indirect material interest.

Note 4. LEASING

Residential Lease Program

The Company offers a solar lease program, in partnership with third-party financial institutions, which allows its residential customers to obtain SunPower systems under lease agreements for terms of up to 20 years. Leases are classified as either operating or sales-type leases in accordance with the relevant accounting guidelines.

Operating Leases

¹  Minimum future rentals on sales-type leases placed in service does not include contingent rentals that may be received from customers under agreements that include performance-based incentives.

Third-Party Financing Arrangements

The Company has entered into multiple facilities under which solar power systems are financed by third-party investors. Under the terms of certain programs the investors make an upfront payment to the Company, which the Company recognizes as a non-recourse liability that will be reduced over the specified term of the program as customer receivables and government incentives are received by the third-party investors. As the non-recourse liability is reduced over time, the Company makes a corresponding reduction in customer and government incentive receivables on its balance sheet. Under this approach, for both operating and sales-type leases the Company continues to account for these arrangements with its residential lease customers in the consolidated financial statements. As of September 28, 2014, and December 29, 2013, the remaining liability to the third-party investors, presented in "Accrued liabilities" and "Other long-term liabilities" on the Company's Consolidated Balance Sheets, was $29.0 million and $46.4 million, respectively (see Note 3).

The Company has entered into a total of seven facilities with third-party investors under which the parties invest in entities that hold SunPower solar power systems and leases with residential customers. The Company holds controlling interests in these less-than-wholly-owned entities and has therefore fully consolidated these entities. The Company accounts

15

for the portion of net assets in the consolidated entities attributable to the investors as "Redeemable noncontrolling interests" and "Noncontrolling interests" in its consolidated financial statements. Noncontrolling interests in subsidiaries that are redeemable at the option of the noncontrolling interest holder are classified as "Redeemable noncontrolling interests in subsidiaries," between liabilities and equity on the Company's Consolidated Balance Sheets. During the three and nine months ended September 28, 2014, the Company received $22.5 million and $75.3 million, respectively, in contributions from investors under the related facilities and attributed $14.7 million and $49.7 million, respectively, in losses to the third-party investors primarily as a result of allocating certain assets, including tax credits, to the investors. By comparison, during the three and nine months ended September 29, 2013, the Company received $29.5 million and $73.4 million, respectively, in contributions from investors under these facilities and attributed $21.0 million and $43.6 million, respectively, in losses to the third-party investors primarily as a result of allocating certain assets, including tax credits, to the investors.

Sale-Leaseback Arrangements

The Company enters into sale-leaseback arrangements under which solar power systems are sold to third parties and subsequently leased back by the Company over minimum lease terms of up to 20 years. Separately, the Company enters into power purchase agreements ("PPAs") with end customers, who host the leased solar power systems and buy the electricity directly from the Company under PPAs with durations of up to 20 years. At the end of the lease term, the Company has the option to purchase the systems at fair value or may be required to remove the systems and return them to the third parties.

The Company has classified its sale-leaseback arrangements of solar power systems not involving integral equipment as operating leases. The deferred profit on the sale of these systems is recognized over the term of the lease. As of September 28, 2014, future minimum lease obligations associated with these systems was $97.5 million, which will be recognized over the minimum lease terms. Future minimum payments to be received from customers under PPAs associated with the solar power systems under sale-leaseback arrangements classified as operating leases will be recognized over the lease terms of up to 20 years and are contingent upon the amounts of energy produced by the solar power systems.

The Company enters into sale-leaseback arrangements under which the systems under the sale-leaseback arrangements have been determined to be integral equipment as defined under the accounting guidance for such transactions. The Company was further determined to have continuing involvement with the solar power systems throughout the lease due to purchase option rights. As a result of such continuing involvement, the Company accounts for each transaction as a financing. Under the financing method, the proceeds received from the sale of the solar power systems are recorded by the Company as financing liabilities and presented within "Other long-term liabilities" in the Company's Consolidated Balance Sheets (see Note 3). The financing liabilities are subsequently reduced by the Company's payments to lease back the solar power systems, less interest expense calculated based on the Company's incremental borrowing rate adjusted to the rate required to prevent negative amortization. The solar power systems under the sale-leaseback arrangements remain on the Company's balance sheet and are classified within "Property, plant and equipment, net" (see Note 3). As of September 28, 2014, future minimum lease obligations for the sale-leaseback arrangements accounted for under the financing method were $80.3 million, which will be recognized over the lease terms of up to 20 years.

Note 5. FAIR VALUE MEASUREMENTS

Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement (observable inputs are the preferred basis of valuation):

• Level 1 — Quoted prices in active markets for identical assets or liabilities.

• Level 2 — Measurements are inputs that are observable for assets or liabilities, either directly or indirectly, other than quoted prices included within Level 1.

• Level 3 — Prices or valuations that require management inputs that are both significant to the fair value measurement and unobservable.

16

Assets and Liabilities Measured at Fair Value on a Recurring Basis

The Company measures certain assets and liabilities at fair value on a recurring basis. There were no transfers between fair value measurement levels during any presented period. The Company did not have any assets or liabilities measured at fair value on a recurring basis requiring Level 3 inputs as of September 28, 2014 or December 29, 2013.

The following table summarizes the Company's assets and liabilities measured and recorded at fair value on a recurring basis as of September 28, 2014 and December 29, 2013, respectively:

¹  The Company's cash equivalents consist of money market fund instruments and commercial paper that are classified as available-for-sale and are highly liquid investments with original maturities of 90 days or less. The Company's money market fund instruments are categorized within Level 1 of the fair value hierarchy because they are valued using quoted market prices for identical instruments in active markets.

Other financial instruments, including the Company's accounts receivable, accounts payable and accrued liabilities, are carried at cost, which generally approximates fair value due to the short-term nature of these instruments.

Debt Derivatives

The 4.50% Bond Hedge (as defined in Note 9) and the embedded cash conversion option within the 4.50% debentures due 2015 (as defined in Note 9) are classified as derivative instruments that require mark-to-market treatment with changes in fair value reported in the Company's Consolidated Statements of Operations. The fair values of these derivative instruments were determined utilizing the following Level 1 and Level 2 inputs:

17

	As of 1
	September 28, 2014			December 29, 2013
Stock price	$	36.11		$	28.91
Exercise price	$	22.53		$	22.53
Interest rate	0.29		%	0.33		%
Stock volatility	54.9		%	57.7		%
Credit risk adjustment	0.21		%	0.71		%
Maturity date	February 18, 2015			February 18, 2015

¹  The valuation model utilizes these inputs to value the right but not the obligation to purchase one share of the Company's common stock at $22.53. The Company utilized a Black-Scholes valuation model to value the 4.50% Bond Hedge and embedded cash conversion option. The underlying input assumptions were determined as follows:

(i) Stock price. The closing price of the Company's common stock on the last trading day of the quarter.

(ii) Exercise price. The exercise price of the 4.50% Bond Hedge and the embedded cash conversion option.

(iii) Interest rate. The Treasury Strip rate associated with the life of the 4.50% Bond Hedge and the embedded cash conversion option.

(iv) Stock volatility. The volatility of the Company's common stock over the life of the 4.50% Bond Hedge and the embedded cash conversion option.

(v) Credit risk adjustment. Represents the weighted average of the credit default swap rate of the counterparties.

Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis

The Company measures certain investments and non-financial assets (including project assets, property, plant and equipment, and other intangible assets) at fair value on a non-recurring basis in periods after initial measurement in circumstances when the fair value of such asset is impaired below its recorded cost.

Held-to-Maturity Debt Securities

The Company's debt securities, classified as held-to-maturity, consist of Philippine government bonds that are maintained as collateral for present and future business transactions within the country. These bonds have maturity dates of up to five years and are classified as "Restricted long-term marketable securities" on the Company's Consolidated Balance Sheets. As of September 28, 2014 and December 29, 2013, these bonds had a carrying value of $7.2 million and $8.9 million respectively. The Company records such held-to-maturity investments at amortized cost based on its ability and intent to hold the securities until maturity. The Company monitors for changes in circumstances and events that would affect its ability and intent to hold such securities until the recorded amortized costs are recovered. No other-than-temporary impairment loss was incurred during any presented period. The held-to-maturity debt securities were categorized in Level 2 of the fair value hierarchy.

Equity and Cost Method Investments

The Company holds equity investments in non-consolidated entities that are accounted for under the both equity and cost method. The Company monitors these investments, which are included in "Other long-term assets" in its Consolidated Balance Sheets, for impairment and records reductions in the carrying values when necessary. Circumstances that indicate an other-than-temporary decline include Level 2 and Level 3 measurements such as the valuation ascribed to the issuing company in subsequent financing rounds, decreases in quoted market prices, and declines in operations of the issuer.

As of September 28, 2014 and December 29, 2013, the Company had $137.1 million and $131.7 million, respectively, in investments accounted for under the equity method (see Note 8). As of September 28, 2014 and December 29, 2013, the Company had $17.3 million and $12.4 million, respectively, in investments accounted for under the cost method.

Note 6. RESTRUCTURING

During fiscal 2012 and 2011, the Company implemented approved restructuring plans, related to all segments, to align with changes in the global solar market, which included the consolidation of the Company's Philippine manufacturing operations as well as actions to accelerate operating cost reduction and improve overall operating efficiency. These restructuring activities were substantially complete as of September 28, 2014. The Company expects to continue to incur costs as it finalizes previous estimates and actions in connection with these plans, primarily due to other costs, such as legal services.

The following table summarizes the restructuring reserve activity during the nine months ended September 28, 2014:

Note 7. COMMITMENTS AND CONTINGENCIES

Facility and Equipment Lease Commitments

The Company leases certain facilities under non-cancellable operating leases from unaffiliated third parties. As of September 28, 2014, future minimum lease payments for facilities under operating leases was $57.5 million, to be paid over the remaining contractual terms of up to 10 years. The Company also leases certain buildings, machinery and equipment under non-cancellable capital leases. As of September 28, 2014, future minimum lease payments for assets under capital leases was $5.3 million, to be paid over the remaining contractual terms of up to 10 years.

Purchase Commitments

The Company purchases raw materials for inventory and manufacturing equipment from a variety of vendors. During the normal course of business, in order to manage manufacturing lead times and help assure adequate supply, the Company enters into agreements with contract manufacturers and suppliers that either allow them to procure goods and services based on specifications defined by the Company, or that establish parameters defining the Company's requirements. In certain instances, these agreements allow the Company the option to cancel, reschedule or adjust the Company's requirements based on its business needs prior to firm orders being placed. Consequently, only a portion of the Company's disclosed purchase commitments arising from these agreements are firm, non-cancellable, and unconditional commitments.

19

The Company also has agreements with several suppliers, including some of its non-consolidated investees, for the procurement of polysilicon, ingots, wafers, and Solar Renewable Energy Credits, among others, which specify future quantities and pricing of products to be supplied by the vendors for periods up to 10 years and provide for certain consequences, such as forfeiture of advanced deposits and liquidated damages relating to previous purchases, in the event that the Company terminates the arrangements.

Future purchase obligations under non-cancellable purchase orders and long-term supply agreements as of September 28, 2014 are as follows:

(In thousands)	2014 (remaining three months)		2015	2016	2017	2018	Thereafter	Total1,2
Future purchase obligations	$	557,109	358,634	324,968	292,181	182,517	341,541	$	2,056,950

¹  Total future purchase obligations as of September 28, 2014 include $91.8 million to related parties.

²  Total future purchase obligations was composed of $230.7 million related to non-cancellable purchase orders and $1.8 billion related to long-term supply agreements.

The Company expects that all obligations related to non-cancellable purchase orders for manufacturing equipment will be recovered through future cash flows of the solar cell manufacturing lines and solar panel assembly lines when such long-lived assets are placed in service. Factors considered important that could result in an impairment review include significant under-performance relative to expected historical or projected future operating results, significant changes in the manner of use of acquired assets, and significant negative industry or economic trends. Obligations related to non-cancellable purchase orders for inventories match current and forecasted sales orders that will consume these ordered materials and actual consumption of these ordered materials are compared to expected demand regularly. The Company anticipates total obligations related to long-term supply agreements for inventories will be recovered because quantities are less than management's expected demand for its solar power products. The terms of the long-term supply agreements are reviewed by management and the Company assesses the need for any accruals for estimated losses on adverse purchase commitments, such as lower of cost or market value adjustments that will not be recovered by future sales prices, forfeiture of advanced deposits and liquidated damages, as necessary.

Advances to Suppliers

As noted above, the Company has entered into agreements with various vendors that specify future quantities and pricing of products to be supplied. Certain agreements also provide for penalties or forfeiture of advanced deposits in the event the Company terminates the arrangements. Under certain agreements, the Company is required to make prepayments to the vendors over the terms of the arrangements. During the three and nine months ended September 28, 2014, the Company made additional advance payments totaling $16.4 million and $49.3 million, respectively, in accordance with the terms of existing long-term supply agreements. As of September 28, 2014 and December 29, 2013, advances to suppliers totaled $401.9 million and $383.3 million, respectively, of which $87.8 million and $58.6 million, respectively, is classified as short-term in the Company's Consolidated Balance Sheets. Two suppliers accounted for 82% and 18% of total advances to suppliers as of September 28, 2014, and 77% and 22% as of December 29, 2013. As of September 28, 2014, the Company has remaining future prepayment obligations totaling $16.4 million through the end of fiscal 2014 .

Advances from Customers

The Company has entered into other agreements with customers who have made advance payments for solar power products and systems. These advances will be applied as shipments of product occur or upon completion of certain project milestones. The estimated utilization of advances from customers as of September 28, 2014 is as follows:

(In thousands)	2014 (remaining three months)		2015	2016	2017	2018	Thereafter	Total
Estimated utilization of advances from customers	$	7,020	34,850	22,713	27,039	27,039	72,106	$	190,767

20

In fiscal 2010, the Company and its joint venture, AUO SunPower Sdn. Bhd. ("AUOSP"), entered into an agreement under which the Company resells to AUOSP polysilicon purchased from a third-party supplier. Advance payments provided by AUOSP related to such polysilicon are then made by the Company to the third-party supplier. These advance payments are applied as a credit against AUOSP’s polysilicon purchases from the Company. Such polysilicon is used by AUOSP to manufacture solar cells which are sold to the Company on a "cost-plus" basis. As of September 28, 2014 and December 29, 2013, outstanding advance payments received from AUOSP totaled $170.8 million and $181.3 million, respectively, of which $17.3 million and $14.0 million, respectively, is classified as short-term in the Company's Consolidated Balance Sheets, based on projected product shipment dates.

Product Warranties

The following table summarizes accrued warranty activity for the three and nine months ended September 28, 2014 and September 29, 2013, respectively:

	Three Months Ended						Nine Months Ended
(In thousands)	September 28, 2014			September 29, 2013			September 28, 2014			September 29, 2013
Balance at the beginning of the period	$	150,793		$	126,293		$	149,372		$	117,172
Accruals for warranties issued during the period	9,112			9,643			18,613			21,995
Settlements made during the period	(5,162		)	(1,161		)	(13,242		)	(4,392		)
Balance at the end of the period	$	154,743		$	134,775		$	154,743		$	134,775

Contingent Obligations

Project agreements often require the Company to undertake obligations including: (i) system output performance guarantees; (ii) system maintenance; (iii) penalty payments or customer termination rights if the system the Company is constructing is not commissioned within specified timeframes or other milestones are not achieved; and (iv) system put-rights whereby the Company could be required to buy back a customer's system at fair value on specified future dates if certain minimum performance thresholds are not met for periods of up to two years. Historically, the Company's systems have performed significantly above the performance guarantee thresholds, and there have been no cases in which the Company has had to buy back a system.

Future Financing Commitments

The Company is required to provide certain funding under the joint venture agreement with AU Optronics Singapore Pte. Ltd. ("AUO") and another unconsolidated investee, subject to certain conditions (see Note 8). As of September 28, 2014, the Company has future financing obligations through 2014 totaling $243.9 million.

Liabilities Associated with Uncertain Tax Positions

Total liabilities associated with uncertain tax positions were $27.1 million and $28.9 million as of September 28, 2014 and December 29, 2013, respectively, and are included in "Other long-term liabilities" in the Company's Consolidated Balance Sheets as they are not expected to be paid within the next 12 months. Due to the complexity and uncertainty associated with its tax positions, the Company cannot make a reasonably reliable estimate of the period in which cash settlement, if any, would be made for its liabilities associated with uncertain tax positions in other long-term liabilities.

Indemnifications

The Company is a party to a variety of agreements under which it may be obligated to indemnify the counterparty with respect to certain matters. Typically, these obligations arise in connection with contracts and license agreements or the sale of assets, under which the Company customarily agrees to hold the other party harmless against losses arising from a breach of warranties, representations and covenants related to such matters as title to assets sold, negligent acts, damage to property, validity of certain intellectual property rights, non-infringement of third-party rights, and certain tax related matters including indemnification to customers under §48(c) solar commercial investment tax credit ("ITC") and Treasury Grant payments under Section 1603 of the American Recovery and Reinvestment Act ("Cash Grant"). In each of these circumstances, payment by the Company is typically subject to the other party making a claim to the Company that is contemplated by and valid under the indemnification provisions of the particular contract, which provisions are typically contract-specific, as well as bringing the claim under the procedures specified in the particular contract. These procedures usually allow the Company to challenge the

21

other party's claims or, in case of breach of intellectual property representations or covenants, to control the defense or settlement of any third party claims brought against the other party. Further, the Company's obligations under these agreements may be limited in terms of activity (typically to replace or correct the products or terminate the agreement with a refund to the other party), duration and/or amounts. In some instances, the Company may have recourse against third parties and/or insurance covering certain payments made by the Company.

In certain limited circumstances the Company has provided indemnification to customers and investors under which the Company is contractually obligated to compensate these parties for losses they may suffer as a result of reductions in benefits received under ITC and Treasury Cash Grant programs. The Company applies for ITC and Cash Grant incentives based on guidance provided by IRS and the Treasury Department, which include assumptions regarding the fair value of the qualified solar power systems, among others.  Certain of the Company’s development agreements, sales-leaseback arrangements, and financing arrangements with investors of its residential lease program, incorporate assumptions regarding the future level of incentives to be received, which in some instances may be claimed directly by its customers and investors. Since the Company cannot determine future revisions to the U.S. Treasury guidelines governing system values or how the IRS will evaluate system values used in claiming ITCs, the Company is unable to reliably estimate the maximum potential future payments that it could have to make under the Company’s contractual investor obligation as of each reporting date.

Legal Matters

Derivative Litigation

Derivative actions purporting to be brought on the Company's behalf have been filed in state and federal courts against several of the Company's current and former officers and directors. The actions arise from the Audit Committee's investigation announcement on November 16, 2009 regarding certain unsubstantiated accounting entries. The California state derivative cases were consolidated as In re SunPower Corp. S'holder Derivative Litig., Lead Case No. 1-09-CV-158522 (Santa Clara Sup. Ct.), and co-lead counsel for plaintiffs have been appointed. The complaints assert state-law claims for breach of fiduciary duty, abuse of control, unjust enrichment, gross mismanagement, and waste of corporate assets. Plaintiffs filed a consolidated amended complaint on March 5, 2012. The federal derivative complaints were consolidated as In re SunPower Corp. S'holder Derivative Litig., Master File No. CV-09-05731-RS (N.D. Cal.), and lead plaintiffs and co-lead counsel were appointed on January 4, 2010. The federal complaints assert state-law claims for breach of fiduciary duty, waste of corporate assets, and unjust enrichment, and seek an unspecified amount of damages. Plaintiffs filed a consolidated complaint on May 13, 2011. A Delaware state derivative case, Brenner v. Albrecht, et al., C.A. No. 6514-VCP (Del Ch.), was filed on May 23, 2011 in the Delaware Court of Chancery. The complaint asserted state-law claims for breach of fiduciary duty and contribution and indemnification, and sought an unspecified amount of damages. On December 19, 2013, the parties executed a stipulated settlement agreement, providing that all claims against all defendants would be released and dismissed with prejudice, and that the Company would not oppose a request by the plaintiffs' counsel for an award of attorneys' fees up to $1 million, one half of which would be paid from the proceeds of directors and officers liability insurance. At a hearing on August 22, 2014, the Superior Court of California for Santa Clara County entered an order providing for final approval of the stipulated settlement and dismissing that action with prejudice. On September 9, 2014, the court in the consolidated federal derivative action dismissed that action with prejudice. Those dismissals are now final. On October 22, 2014, the Delaware Chancery Court entered an order dismissing the Delaware derivative action with prejudice.

Tax Benefit Indemnification Litigation

On March 19, 2014, the Company received notice that a lawsuit had been filed by NRG Solar LLC (“NRG”) against SunPower Corporation, Systems, a wholly-owned subsidiary of the Company (“SunPower Systems”), in the Superior Court of Contra Costa County, California.  The complaint asserts that, according to the indemnification provisions in the contract pertaining to SunPower Systems’ sale of a large California solar project to NRG, SunPower Systems owes NRG $75 million in connection with certain tax benefits associated with the project that were approved by the Treasury Department for an amount that was less than expected. The Company does not believe that the facts support NRG’s claim under the operative indemnification provisions and intends to vigorously contest the claim. On May 5, 2014, SunPower Systems filed a demurrer to NRG’s complaint, which remains pending. The Court sustained the demurrer with leave to amend. NRG filed its amended complaint on September 3, 2014. The Company filed a demurrer to NRG's amended complaint on September 22, 2014, and that demurrer is scheduled to be heard on November 18, 2014. The Court has not yet set a trial date or case schedule. The company is currently unable to determine if the resolution of this matter will have an adverse effect on the company's financial position, liquidity or results of operations. 

22

Other Litigation

The Company is also a party to various other litigation matters and claims that arise from time to time in the ordinary course of its business. While the Company believes that the ultimate outcome of such matters will not have a material adverse effect on the Company, their outcomes are not determinable and negative outcomes may adversely affect the Company's financial position, liquidity or results of operations.

Note 8. EQUITY METHOD INVESTMENTS

As of September 28, 2014 and December 29, 2013, the Company's carrying value of its equity method investments totaled $137.1 million and $131.7 million, respectively, and is classified as “Other long-term assets” in its Consolidated Balance Sheets. The Company's share of its earnings (loss) from equity method investments is reflected as "Equity in earnings of unconsolidated investees" in its Consolidated Statement of Operations.

Equity Investment and Joint Venture with AUOSP

In fiscal 2010, the Company, AUO and AU Optronics Corporation, the ultimate parent company of AUO ("AUO Taiwan"), formed the joint venture AUOSP. The Company and AUO each own 50% of the joint venture AUOSP. AUOSP owns a solar cell manufacturing facility in Malaysia and manufactures solar cells and sells them on a "cost-plus" basis to the Company and AUO.

In connection with the joint venture agreement, the Company and AUO also entered into licensing and joint development, supply, and other ancillary transaction agreements. Through the licensing agreement, the Company and AUO licensed to AUOSP, on a non-exclusive, royalty-free basis, certain background intellectual property related to solar cell manufacturing (in the case of the Company), and manufacturing processes (in the case of AUO). Under the seven-year supply agreement with AUOSP, renewable by the Company for one-year periods thereafter, the Company is committed to purchase 80% of AUOSP's total annual output allocated on a monthly basis to the Company. The Company and AUO have the right to reallocate supplies from time to time under a written agreement. In fiscal 2010, the Company and AUOSP entered into an agreement under which the Company will resell to AUOSP polysilicon purchased from a third-party supplier and AUOSP will provide prepayments to the Company related to such polysilicon, which prepayment will then be made by the Company to the third-party supplier.

The Company and AUO are not permitted to transfer any of AUOSP's shares held by them, except to each other. In the joint venture agreement, the Company and AUO agreed to each contribute additional amounts through 2014 amounting to $241.0 million, or such lesser amount as the parties may mutually agree. In addition, if AUOSP, the Company or AUO requests additional equity financing to AUOSP, then the Company and AUO will each be required to make additional cash contributions of up to $50.0 million in the aggregate.

The Company has concluded that it is not the primary beneficiary of AUOSP since, although the Company and AUO are both obligated to absorb losses or have the right to receive benefits, the Company alone does not have the power to direct the activities of AUOSP that most significantly impact its economic performance. In making this determination the Company considered the shared power arrangement, including equal board governance for significant decisions, elective appointment, and the fact that both parties contribute to the activities that most significantly impact the joint venture's economic performance. The Company accounts for its investment in AUOSP using the equity method as a result of the shared power arrangement. As of September 28, 2014, the Company's maximum exposure to loss as a result of its equity investment in AUOSP is limited to the carrying value of the investment.

Equity Investment in Huaxia CPV (Inner Mongolia) Power Co., Ltd. ("CCPV")

In December 2012, the Company entered into an agreement with Tianjin Zhonghuan Semiconductor Co. Ltd., Inner Mongolia Power Group Co. Ltd. and Hohhot Jinqiao City Development Company Co., Ltd. to form CCPV, a jointly owned entity to manufacture and deploy the Company's C-7 Tracker concentrator technology in Inner Mongolia and other regions in China. CCPV is based in Hohhot, Inner Mongolia. The establishment of the entity was subject to approval of the Chinese government, which was received in the fourth quarter of fiscal 2013. In December 2013, the Company made a $16.4 million equity investment in CCPV, for a 25% equity ownership.

23

The Company has concluded that it is not the primary beneficiary of CCPV since, although the Company is obligated to absorb losses and has the right to receive benefits, the Company alone does not have the power to direct the activities of CCPV that most significantly impact its economic performance. The Company accounts for its investment in CCPV using the equity method since the Company is able to exercise significant influence over CCPV due to its board position.

Equity Investment in Diamond Energy Pty Ltd. ("Diamond Energy")

In October 2012, the Company made a $3.0 million equity investment in Diamond Energy, an alternative energy project developer and clean electricity retailer headquartered in Melbourne, Australia, in exchange for a 25% equity ownership.

The Company has concluded that it is not the primary beneficiary of Diamond Energy since, although the Company is obligated to absorb losses and has the right to receive benefits, the Company alone does not have the power to direct the activities of Diamond that most significantly impact its economic performance. The Company accounts for its investment in Diamond using the equity method since the Company is able to exercise significant influence over Diamond due to its board position.

¹  The fair value of the convertible debt was determined using Level 1 inputs based on quarterly market prices as reported by an independent pricing source.

The Company's outstanding convertible debentures are senior, unsecured obligations of the Company, ranking equally with all existing and future senior unsecured indebtedness of the Company.

0.875% Debentures Due 2021

In June 2014, the Company issued $400.0 million in principal amount of its 0.875% debentures due 2021. Interest is payable semi-annually, beginning on December 1, 2014. Holders may exercise their right to convert the debentures at any time into shares of the Company's common stock at an initial conversion price approximately equal to $48.76 per share, subject to adjustment in certain circumstances. If not earlier repurchased or converted, the 0.875% debentures due 2021 mature on June 1, 2021.

0.75% Debentures Due 2018

In May 2013, the Company issued $300.0 million in principal amount of its 0.75% debentures due 2018. Interest is payable semi-annually, beginning on December 1, 2013. Holders may exercise their right to convert the debentures at any time into shares of the Company's common stock at an initial conversion price approximately equal to $24.95 per share, subject to adjustment in certain circumstances. If not earlier repurchased or converted, the 0.75% debentures due 2018 mature on June 1, 2018.

4.50% Debentures Due 2015

In 2010, the Company issued $250.0 million in principal amount of its 4.50% senior cash convertible debentures ("4.50% debentures due 2015"). Interest is payable semi-annually, beginning on September 15, 2010. If not earlier repurchased or converted, the 4.50% debentures due 2015 mature on March 15, 2015. The 4.50% debentures due 2015 are convertible, upon certain events and restrictions, only into cash, and not into shares of the Company's common stock (or any other securities) at an initial conversion price of $22.53 per share. The conversion price is subject to adjustment in certain events, such as distributions of dividends or stock splits. Upon conversion, the Company will deliver cash in an amount calculated by reference to the price of its common stock over the applicable observation period.

The embedded cash conversion option is a derivative instrument (derivative liability) that is required to be separated from the 4.50% debentures due 2015. The fair value of the derivative liability is classified within "Other long-term liabilities"

25

on the Company's Consolidated Balance Sheets. Changes in the fair value of the derivative liability are reported in the Company's Consolidated Statements of Operations until such transaction settles or expires.

During the three and nine months ended September 28, 2014, the Company recognized a non-cash gain of $56.7 million and non-cash loss of $44.6 million, respectively, recorded in "Other, net" in the Company's Consolidated Statement of Operations related to the change in fair value of the embedded cash conversion option. During the three and nine months ended September 29, 2013 the Company recognized a non-cash loss of $36.0 million and $94.3 million, respectively, recorded in "Other, net" in the Company's Consolidated Statement of Operations related to the change in fair value of the embedded cash conversion option.

Call Spread Overlay with Respect to 4.50% Debentures

Concurrently with the issuance of the 4.50% debentures due 2015, the Company entered into privately-negotiated convertible debenture hedge transactions (collectively, the "4.50% Bond Hedge") and warrant transactions (collectively, the "4.50% Warrants" and together with the 4.50% Bond Hedge, the “CSO2015”), with certain of the initial purchasers of the 4.50% debentures due 2015 or their affiliates. The CSO2015 transactions represent a call spread overlay with respect to the 4.50% debentures due 2015, whereby the cost of the 4.50% Bond Hedge purchased by the Company to cover the cash outlay upon conversion of the debentures is reduced by the sales prices of the 4.50% Warrants. Assuming full performance by the counterparties (and 4.50% Warrants strike prices above the conversion price of the 4.50% debentures due 2015), the transactions effectively reduce the Company's potential payout over the principal amount on the 4.50% debentures due 2015 upon conversion of the 4.50% debentures due 2015.

Under the terms of the 4.50% Bond Hedge, the Company bought options to acquire, at an exercise price of $22.53 per share, subject to customary adjustments for anti-dilution and other events, cash in an amount equal to the market value of up to 11.1 million shares of the Company's common stock. Under the terms of the 4.50% Warrants the Company sold warrants to acquire, at an exercise price of $24.00 per share, up to 11.1 million shares of the Company's common stock. Each 4.50% Bond Hedge and 4.50% Warrant transaction is a separate transaction, entered into by the Company with each counterparty, and is not part of the terms of the 4.50% debentures due 2015.

The 4.50% Bond Hedge, which is indexed to the Company's common stock, is a derivative instrument that requires mark-to-market accounting treatment due to the cash settlement features until such transactions settle or expire. The fair value of the 4.50% Bond Hedge is classified as "Other long-term assets" in the Company's Consolidated Balance Sheets.

During the three and nine months ended September 28, 2014, the Company recognized a non-cash loss of $56.7 million and non-cash gain of $44.6 million, respectively, in "Other, net" in the Company's Consolidated Statement of Operations related to the change in fair value of the 4.50% Bond Hedge. During the three and nine months ended September 29, 2013, the Company recognized a non-cash gain of $36.0 million and $94.3 million, respectively, in "Other, net" in the Company's Consolidated Statement of Operations related to the change in fair value of the 4.50% Bond Hedge.

4.75% Debentures Due 2014

In May 2009, the Company issued $230.0 million in principal amount of its 4.75% senior convertible debentures ("4.75% debentures due 2014"). Interest on the 4.75% debentures due 2014 was payable semi-annually, beginning October 15, 2009. Holders of the 4.75% debentures due 2014 were able to exercise their right to convert the debentures at any time into shares of the Company's common stock at a conversion price equal to $26.40 per share, subject to adjustment upon certain events. In April 2014, the 4.75% debentures due 2014 matured. During April 2014, the Company issued approximately 7.1 million shares of its common stock to holders that exercised conversion rights prior to their maturity and paid holders an aggregate of $41.7 million in cash in connection with the settlement of the remaining 4.75% debentures. Subsequent to the maturity date, no 4.75% debentures remained outstanding.

Call Spread Overlay with Respect to the 4.75% Debentures

Concurrently with the issuance of the 4.75% debentures due 2014, the Company entered into certain convertible debenture hedge transactions (the "4.75% Bond Hedge") and warrant transactions (the "4.75% Warrants") with affiliates of certain of the underwriters of the 4.75% debentures due 2014 (together, the "CSO2014"), whereby the cost of the 4.75% Bond Hedges purchased by the Company to cover the potential share outlays upon conversion of the debentures was reduced by the sales prices of the 4.75% Warrants. The CSO2014 were not subject to mark-to-market accounting treatment since they could only be settled by issuance of the Company's common stock.

26

The 4.75% Bond Hedge allowed the Company to purchase up to 8.7 million shares of the Company's common stock, on a net share basis. Each 4.75% Bond Hedge and 4.75% Warrant was a separate transaction, entered into by the Company with each counterparty, and was not part of the terms of the 4.75% debentures due 2014. The exercise prices of the 4.75% Bond Hedge were $26.40 per share of the Company's common stock, subject to customary adjustment for anti-dilution and other events. In February 2014, the parties agreed to unwind the 4.75% Bond Hedge in full for a total cash settlement of $68.8 million, calculated by reference to the weighted price of the Company's common stock on the settlement day, received by the Company.

Under the 4.75% Warrants, the Company sold warrants to acquire up to 8.7 million shares of the Company's common stock at an exercise price of $26.40 per share of the Company's common stock, subject to adjustment for certain anti-dilution and other events. In February 2014, the parties agreed to unwind the 4.75% Warrants in full for a total cash settlement of $81.1 million, calculated by reference to the weighted price of the Company's common stock on the settlement date, paid by the Company.

Other Debt and Credit Sources

Mortgage Loan Agreement with IFC

In May 2010, the Company entered into a mortgage loan agreement with IFC. Under the loan agreement, we borrowed $75.0 million and are required to repay the amount borrowed starting two years after the date of borrowing, in 10 equal semi-annual installments. The Company is required to pay interest of LIBOR plus 3% per annum on outstanding borrowings; a front-end fee of 1% on the principal amount of borrowings at the time of borrowing; and a commitment fee of 0.5% per annum on funds available for borrowing and not borrowed. The Company may prepay all or a part of the outstanding principal, subject to a 1% prepayment premium. The Company has pledged certain assets as collateral supporting its repayment obligations (see Note 3). As of both September 28, 2014 and December 29, 2013, the Company had restricted cash and cash equivalents of $9.2 million related to the IFC debt service reserve, which is the amount, as determined by IFC, equal to the aggregate principal and interest due on the next succeeding interest payment date.

Loan Agreement with California Enterprise Development Authority ("CEDA")

In 2010, the Company borrowed the proceeds of the $30.0 million aggregate principal amount of CEDA's tax-exempt Recovery Zone Facility Revenue Bonds (SunPower Corporation - Headquarters Project) Series 2010 (the "Bonds") maturing April 1, 2031 under a loan agreement with CEDA. The Bonds mature on April 1, 2031, bear interest at a fixed rate of 8.50% through maturity, and include customary covenants and other restrictions on the Company.

July 2013 Revolving Credit Facility with Credit Agricole

In July 2013, the Company entered into a revolving credit facility with Credit Agricole, as administrative agent, and certain financial institutions, under which the Company may borrow up to $250.0 million. On August 26, 2014, the Company entered into an amendment to the revolving credit facility that, among other things, extends the maturity date of the facility from July 3, 2016 to August 26, 2019 (the "Maturity Date"). Amounts borrowed may be repaid and reborrowed until the Maturity Date. The Company may request increases to the available capacity of the revolving credit facility to an aggregate of $300.0 million, subject to the satisfaction of certain conditions. The revolving credit facility includes representations, covenants, and events of default customary for financing transactions of this type.

The revolving credit facility was entered into in conjunction with the delivery by Total S.A. of a guarantee of the Company's obligations under the related facility. On January 31, 2014, as contemplated by the facility, (i) the Company's obligations under the facility became secured by a pledge of certain accounts receivable and inventory; (ii) certain of the Company's subsidiaries entered into guarantees of the facility; and (iii) Total S.A.'s guarantee of the Company's obligations under the facility expired. Until the expiration of the guarantee on January 31, 2014, the Company was required to pay Total S.A. an annual guarantee fee of 2.75% of the outstanding amount under the revolving credit facility.

Before January 31, 2014, the Company was required to pay interest on outstanding borrowings and fees of (a) with respect to any LIBOR rate loan, 0.60% plus the LIBOR rate divided by a percentage equal to one minus the stated maximum rate of all reserves required to be maintained against "Eurocurrency liabilities" as specified in Regulation D; (b) with respect to any alternative base rate loan, 0.25% plus the greater of (1) the prime rate, (2) the Federal funds rate plus 0.50%, and (3) the one month LIBOR rate plus 1%; and (c) a commitment fee of 0.06% per annum on funds available for borrowing and not borrowed.

27

After January 31, 2014, the Company is required to pay interest on outstanding borrowings and fees of (a) with respect to any LIBOR rate loan, an amount ranging from 1.50% to 2.00% (depending on the Company's leverage ratio from time to time) plus the LIBOR rate divided by a percentage equal to one minus the stated maximum rate of all reserves required to be maintained against “Eurocurrency liabilities” as specified in Regulation D; (b) with respect to any alternate base rate loan, an amount ranging from 0.50% to 1.00% (depending on the Company's leverage ratio from time to time) plus the greater of (1) the prime rate, (2) the Federal Funds rate plus 0.50%, and (3) the one-month LIBOR rate plus 1%; and (c) a commitment fee ranging from 0.25% to 0.35% (depending on the Company's leverage ratio from time to time) per annum on funds available for borrowing and not borrowed.

As of September 28, 2014 and December 29, 2013, the Company had no outstanding borrowings under the revolving credit facility.

Liquidity Support Agreement with Total S.A.

In February 2012, the Company entered into a Liquidity Support Agreement with Total S.A. and the DOE, and a series of related agreements with Total S.A. and Total, under which Total S.A. agreed to provide the Company, or cause to be provided, additional liquidity under certain circumstances. The Liquidity Support Agreement was terminated in the first quarter of fiscal 2014. There were no outstanding guarantees or debt under the agreement upon termination (see Note 2).

Project Financing

In order to facilitate the construction and sale of certain solar projects, the Company obtains non-recourse project loans from third-party financial institutions that are contemplated as part of the structure of the sales transaction. The customer, which is not a related party to either the financial institution or the Company, in certain circumstances is permitted to assume the loans at the time that the project entity is sold to the customer. During fiscal 2013, the Company entered into a project loan with a consortium of lenders to facilitate the development of a 10 MW utility and power plant projects under construction in Israel. During the first quarter of fiscal 2014, the Company sold the Israeli project. The related loan, amounting to ILS 141.8 million (approximately $40.7 million based on the exchange rate at the time of sale), and accrued and unpaid interest was assumed by the customer. In instances where the debt is issued as a form of pre-established customer financing, subsequent debt assumption is reflected as a financing outflow and operating inflow for purposes of the statement of cash flows to reflect the substance of the assumption as a facilitation of customer financing from a third-party.

Other Debt

During fiscal 2014, the Company entered into two long-term non-recourse loans to finance solar power systems and leases under its residential lease program. In fiscal 2014 the Company drew down $74.8 million of proceeds, net of issuance costs, under the loan agreements.

During fiscal 2013, the Company entered into a long-term non-recourse loan agreement with a third-party financial institution to finance a 5.4 MW utility and power plant operating in Arizona. The outstanding balance of the loan as of September 28, 2014 was $8.7 million.

Other debt is further composed of non-recourse project loans in EMEA which are scheduled to mature through 2028.

August 2011 Letter of Credit Facility with Deutsche Bank

In August 2011, the Company entered into a letter of credit facility agreement with Deutsche Bank, as administrative agent, and certain financial institutions. Payment of obligations under the letter of credit facility is guaranteed by Total S.A. pursuant to the Credit Support Agreement (see Note 2). The letter of credit facility provides for the issuance, upon request by the Company, of letters of credit by the issuing banks thereunder in order to support certain obligations of the Company, in an aggregate amount not to exceed $878.0 million for the period from January 1, 2014 through December 31, 2014. Aggregate letter of credit amounts may be increased upon the agreement of the parties but, otherwise, may not exceed (i) $936.0 million for the period from January 1, 2015 through December 31, 2015, and (ii) $1.0 billion for the period from January 1, 2016 through June 28, 2016.

As of September 28, 2014 and December 29, 2013, letters of credit issued and outstanding under the August 2011 letter of credit facility with Deutsche Bank totaled $730.0 million and $736.0 million, respectively.

28

September 2011 Letter of Credit Facility with Deutsche Bank Trust

In September 2011, the Company entered into a letter of credit facility with Deutsche Bank Trust which provides for the issuance, upon request by the Company, of letters of credit to support obligations of the Company in an aggregate amount not to exceed $200.0 million. Each letter of credit issued under the facility is fully cash-collateralized and the Company has entered into a security agreement with Deutsche Bank Trust, granting them a security interest in a cash collateral account established for this purpose.

As of September 28, 2014 and December 29, 2013, letters of credit issued and outstanding under the Deutsche Bank Trust facility amounted to $1.2 million and $2.4 million, respectively, which were fully collateralized with restricted cash on the Consolidated Balance Sheets.

Foreign Currency Exchange Risk

Designated Derivatives Hedging Cash Flow Exposure

The Company's cash flow exposure primarily relates to anticipated third-party foreign currency revenues and expenses. To protect financial performance, the Company enters into foreign currency forward and option contracts designated as cash flow hedges to hedge certain forecasted revenue transactions denominated in currencies other than their functional currencies.

As of September 28, 2014, the Company had designated outstanding cash flow hedge option contracts and forward contracts with an aggregate notional value of $46.6 million and $19.1 million, respectively. As of December 29, 2013, the Company had designated outstanding cash flow hedge option contracts and forward contracts with an aggregate notional value of $105.9 million and $42.8 million, respectively. The Company designates either gross external or intercompany revenue up to its net economic exposure. These derivatives have a maturity of 12 months or less and consist of foreign currency option and forward contracts. The effective portion of these cash flow hedges is reclassified into revenue when third-party revenue is recognized in the Consolidated Statements of Operations.

Non-Designated Derivatives Hedging Transaction Exposure

Derivatives not designated as hedging instruments consist of forward and option contracts used to hedge re-measurement of foreign currency denominated monetary assets and liabilities primarily for intercompany transactions, receivables from customers, and payables to third parties. Changes in exchange rates between the Company's subsidiaries' functional currencies and the currencies in which these assets and liabilities are denominated can create fluctuations in the Company's reported consolidated financial position, results of operations and cash flows. As of September 28, 2014, the Company held option contracts and forward contracts with an aggregate notional value of zero and $53.2 million, respectively, to hedge balance sheet exposure. The maturity dates of these contracts range from September 2014 to March 2015. The Company held option contracts and forward contracts with an aggregate notional value of $9.4 million and $32.1 million, respectively, as of December 29, 2013, to hedge balance sheet exposure.

Credit Risk

The Company's option and forward contracts do not contain any credit-risk-related contingent features. The Company is exposed to credit losses in the event of nonperformance by the counterparties to these option and forward contracts. The Company enters into derivative contracts with high-quality financial institutions and limits the amount of credit exposure to any single counterparty. In addition, the derivative contracts are limited to a time period of 12 months or less and the Company continuously evaluates the credit standing of its counterparties.

Note 11. INCOME TAXES

In the three and nine months ended September 28, 2014, the Company's income tax benefit of $8.3 million and $2.9 million, respectively, on an income before income taxes and equity in earnings of unconsolidated investees of $7.3 million and $53.2 million, respectively, was primarily due to an increase in forecasted profit before tax for the fiscal period, provision to return adjustments, and acquired deferred tax liabilities used to reduce the valuation allowance, partially offset by state taxes and the recognition of previously unrecognized tax benefits. In the three and nine months ended September 29, 2013, the Company's income tax benefit of $4.6 million and income tax provision of $2.9 million, respectively, on an income before income taxes and equity in earnings of unconsolidated investees of $81.2 million and $30.3 million respectively, was primarily due to projected tax expense in profitable foreign jurisdictions as well as minimum taxes and the recognition of a previously unrecognized tax benefit.

Note 12. NET INCOME PER SHARE

The Company calculates net income per share by dividing earnings allocated to common stockholders by the weighted average number of common shares outstanding for the period.

Diluted weighted average shares is computed using basic weighted average shares plus any potentially dilutive securities outstanding during the period using the treasury-stock-type method and the if-converted method, except when their effect is anti-dilutive. Potentially dilutive securities include stock options, restricted stock units, the Upfront Warrants held by Total, warrants associated with the CSO2015 and CSO2014, and senior convertible debentures.

Dilutive net income per share	$	0.20	$	0.73	$	0.72	$	0.55

The Upfront Warrants allow Total to acquire up to 9,531,677 shares of the Company's common stock at an exercise price of $7.8685. Holders of the Warrants under the CSO2015 and CSO2014, may acquire up to 11.1 million and 8.7 million shares, respectively, of the Company's common stock at an exercise price of $24.00 and $26.40, respectively. If the market price per share of the Company's common stock for the period exceeds the established strike price of the respective warrants, they will have a dilutive effect on its diluted net income per share using the treasury-stock-type method. In February 2014, the CSO2014 was settled, leaving none of the related Warrants outstanding (see Note 9).

Holders of the Company's 0.875% debentures due 2021, 0.75% debentures due 2018, and the 4.75% debentures due 2014 may convert the debentures into shares of the Company's common stock, at the applicable conversion rate, at any time on or prior to maturity. These debentures are included in the calculation of diluted net income per share if they were outstanding during the period presented and if their inclusion is dilutive under the if-converted method. In April 2014, the 4.75% debentures matured and were fully settled in both cash and shares of the Company's common stock during the quarter (see Note 9).

32

Holders of the Company's 4.50% debentures due 2015 may, under certain circumstances at their option, convert the debentures into cash, and not into shares of the Company's common stock (or any other securities). Therefore, the 4.50% debentures due 2015 are excluded from the net income per share calculation.

The following is a summary of outstanding anti-dilutive potential common stock that was excluded from income per diluted share in the following periods:

	Three Months Ended		Nine Months Ended

Note 14. SEGMENT INFORMATION

The Company's President and Chief Executive Officer, as the chief operating decision maker ("CODM"), has organized the Company, manages resource allocations and measures performance of the Company's activities among three regional segments: (i) the Americas Segment, (ii) the EMEA Segment, and (iii) the APAC Segment. The Americas Segment includes both North and South America. The EMEA Segment includes European countries, as well as the Middle East and Africa. The APAC segment includes all Asia-Pacific countries.

The CODM assesses the performance of the three regional segments using information about their revenue and gross margin after certain adjustments to reflect the substance of the revenue transactions for certain utility and power plant projects, and adding back certain non-cash expenses such as stock-based compensation expense and interest expense, as well as other items including gain on contract termination, loss on change in European government incentives, accelerated depreciation associated with the Company's manufacturing step reduction program, and amortization of other intangible assets. The CODM does not review asset information by segment.

The following tables present information by region; including revenue, gross margin, and depreciation and amortization.

Overview

SunPower is a leading global energy services company dedicated to changing the way the world is powered. We believe SunPower's breakthrough technology is unmatched in long-term reliability, efficiency and guaranteed performance. Through design, manufacturing, installation and ongoing maintenance and monitoring, SunPower provides its proprietary, high-performance solar technology to residential, commercial and utility customers worldwide. With industry-leading conversion efficiencies, we believe our Maxeon solar cells perform better, are tested more extensively and improved continuously to deliver maximum return on investment when compared with our competitors. We believe that there are several factors that set us apart when compared with various competitors:

– A go-to-market platform that is broad and deep, reflecting our long-standing experience in rooftop and ground mount channels, including turn-key systems:

• Cutting-edge systems designed to meet customer needs and reduce cost, including non-penetrating, fast roof installation technologies;

• Expanded reach enhanced by Total S.A.'s long-standing presence in many countries where significant solar installation goals are being established; and

• End-to-end solutions management capabilities, including operations and maintenance of some of the world's largest solar power systems.

– A technological advantage, which includes being the leading solar company manufacturing back-contact, back-junction cells enabling our panels to produce more electricity, last longer and resist degradation more effectively:

• Superior performance, including the ability to generate up to 50% more power per unit area than conventional solar cells;

• Superior aesthetics, with our uniformly black surface design that eliminates highly visible reflective grid lines and metal interconnection ribbons;

• Superior reliability, as confirmed by multiple independent reports and internal reliability data;

• Superior energy production per rated watt of power, as confirmed by multiple independent reports;

• The ability to transport more KW per pound using less packaging, resulting in lower distribution costs and environmental waste; and

• More efficient use of silicon, a key raw material used in the manufacture of solar cells;

– Costs that are decreasing faster and more steadily in comparison to many other solar companies as a result of an aggressive, but we believe achievable, cost reduction plan as well as value that benefits all customers:

• We offer a significantly lower area-related cost structure for our customers because our solar panels require a substantially smaller roof or land area than conventional solar technology and half or less of the roof or land area of many commercial solar thin film technologies;

• Our leasing program offers customers high efficiency solar products for no money down at competitive energy rates; and

• Our solar power systems are designed to generate electricity over a system life typically exceeding 25 years.

Segments Overview

We manage resource allocations and measure performance among three regional segments: (i) the Americas Segment, (ii) the EMEA Segment, and (iii) the APAC Segment. The Americas Segment includes both North and South America. The EMEA Segment includes European countries, as well as the Middle East and Africa. The APAC Segment includes all Asia-Pacific countries.

37

Unit of Power

When referring to our solar power systems, our facilities’ manufacturing capacity, and total sales, the unit of electricity in watts for kilowatts ("KW"), megawatts ("MW"), and gigawatts ("GW") is direct current ("dc").

Levelized Cost of Energy ("LCOE")

LCOE is a measure used to evaluate the life-cycle energy cost and life-cycle energy production of an energy producing system. It allows alternative technologies to be compared when different scales of operation, investment, or operating time periods exist. The LCOE equation captures capital costs and ongoing system-related costs, along with the amount of electricity produced, and converts them into a common metric. Key drivers for LCOE reduction for photovoltaic products include panel efficiency, capacity factors, reliable system performance, and the life of the system.

Customer Cost of Electricity ("CCOE")

Our customers are focused on reducing their overall cost of energy by intelligently integrating solar and other distributed generation, energy efficiency, energy management, and energy storage systems with their existing utility-provided energy. CCOE is a measure used to evaluate a customer’s overall cost of energy, taking into account the cost impact of each individual generation source (including the utility), energy storage systems, and energy management systems.  The CCOE metric allows a customer to compare different portfolios of generation sources, energy storage, and energy management, and to tailor towards optimization.  The CCOE equation includes capital costs and ongoing operating costs, along with the amount of electricity produced, stored, saved, or re-sold, and converts all of these variables into a common metric.

Seasonal Trends

Our business is subject to industry-specific seasonal fluctuations including changes in weather patterns and economic incentives, among others. Sales have historically reflected these seasonal trends with the largest percentage of total revenues realized during the last two calendar quarters of a fiscal year. The construction of solar power systems or installation of solar power products and related revenue may decline during cold winter months. In the United States, many customers make purchasing decisions towards the end of the year in order to take advantage of tax credits or for other budgetary reasons.

Fiscal Years

We have a 52-to-53-week fiscal year that ends on the Sunday closest to December 31. Accordingly, every fifth or sixth year will be a 53-week fiscal year. Both fiscal years 2014 and 2013 are 52-week fiscal years. The third quarter of fiscal 2014 ended on September 28, 2014, while the third quarter of fiscal 2013 ended on September 29, 2013. Both the third quarter of fiscal 2014 and 2013 were 13-week quarters. Fiscal 2014 will end on December 28, 2014.

Outlook

While remaining focused on our U.S. market, we plan to continue to expand our business in growing and sustainable markets, including Africa, Australia, China, and South America. Through our investment in Huaxia CPV (Inner Mongolia) Power Co., Ltd., with partners in China, we plan to manufacture and deploy the Company's C-7 Tracker systems in Inner Mongolia and other regions in China. We plan to expand our solar cell manufacturing capacity through the construction of a facility in the Philippines with a planned annual capacity of 350 MW once fully operational in fiscal 2015.

SunPower continues to improve our unique, differentiated solar cell and panel technology. Our new residential product line includes our SunPower X-Series Solar Panels with demonstrated average panel efficiencies exceeding 21.5%. We are focused on reducing the cost of our solar panels and systems and are working with our suppliers and partners along all steps of the value chain to reduce costs by improving manufacturing technologies and expanding economies of scale. We continue to emphasize improvement of our solar cell efficiency and LCOE performance through enhancement of our existing products, development of new products and reduction of manufacturing cost and complexity in conjunction with our overall cost-control strategies. By 2015, we expect to reach production panel efficiencies of 23% using a simplified, lower cost manufacturing process. We further see significant and increasing opportunity in technologies and capabilities adjacent to our core product offerings, including the integration of energy storage and energy management functionality into our systems.

Projects Sold / Under Contract

The table below presents significant construction and development projects sold or under contract as of September 28, 2014:

Project	Location	Size (MW)	Third Party Owner / Purchaser	Power Purchase Agreement(s)	Expected Completion of Revenue Recognition
Solar Star Projects	California	748	MidAmerican Energy Holdings Company	Southern California Edison	2015
Project Salvador1	Chile	70	Total S.A., Etrion Corporation, Solventus Energias Renovables	N/A2	2015

¹  We have entered into an EPC agreement and a long-term fixed price operations and maintenance ("O&M") agreement with the owners of Project Salvador.

²  Electricity produced will be sold on the spot market.

As of September 28, 2014, an aggregate of approximately $1.0 billion of remaining revenue is expected to be recognized on projects reflected in the table above through the expected completion dates noted. Projects will be removed from the table above in the period in which substantially all of the revenue for such project has been recognized.

Projects with Executed Power Purchase Agreements - Not Sold / Not Under Contract

The table below presents significant construction and development projects with executed power purchase agreements, but not sold or under contract as of September 28, 2014:

Project	Location	Size (MW)	Power Purchase Agreement(s)	Expected Completion of Revenue Recognition1
Henrietta Solar Project	California	128	PG&E	2016
Quinto Solar Project	California	135	Southern California Edison	2015
Hooper Solar Project	Colorado	60	Public Service Company of Colorado	2016

¹  Expected completion of revenue recognition assumes completion of construction and sale of the project in the stated fiscal year.

Our project pipeline extends beyond the projects represented in the tables above. Significant projects with development and milestone activities in progress will be excluded from the table above until an associated power purchase agreement has been executed.

Residential Leasing Program

In fiscal 2011, we launched our residential lease program with dealers in the United States, in partnership with a third-party financial institution, which allows customers to obtain SunPower systems under lease agreements with terms of up to 20 years, subject to financing availability. We have entered into multiple facilities with financial institutions that will provide financing to support additional residential solar lease projects. The program includes system maintenance and warranty

39

coverage as well as an early buy-out option after six years or at any time when the lessees sell their home. Leases are classified as either operating or sales-type leases in accordance with the relevant accounting guidelines. We plan to continue to expand our customer finance programs in the United States as well as other international markets.

The program does not yet represent a material portion of our revenue. However, we may face additional material risks as the program expands, including our ability to obtain additional financing partners as well as our ability to collect finance and rent receivables in view of the general challenging credit markets worldwide. We believe that our concentration of credit risk is limited because of our large number of customers, credit quality of the customer base, small account balances for most of these customers, and customer geographic diversification. We have applied and will apply for the §48(c) solar commercial investment tax credit ("ITC") and Treasury Grant payments under Section 1603 of the American Recovery and Reinvestment Act (the "Cash Grant"), which are administered by the U.S. Internal Revenue Service ("IRS") and Treasury Department, respectively, for residential leases. We have structured the tax incentive applications, both in timing and amount, to be in accordance with the guidance provided by Treasury and IRS. If the amount or timing of the ITC or Cash Grant payments received in connection with the residential lease program varies from what we have projected, this may impact our revenues and margins and we may have to recognize losses, which may adversely impact our results of operations and cash flows. We make certain assumptions in accounting for the residential lease program, including, among others, the residual value of the leased systems. As the residential lease program grows, if the residual value of leased systems does not materialize as assumed, our results of operations would be adversely affected.

Total revenue	$	662,734	$	657,120	1%	$	1,863,027	$	1,869,069	—%

Total Revenue:  Our total revenue remained flat during the three and nine months ended September 28, 2014 as compared to the three and nine months ended September 29, 2013. Flat revenue over the three month period was primarily due to an increase in revenue recognition on solar power systems, offset by decreased revenue related to solar power products, whereas flat revenue during the nine month period was primarily due to a decrease in revenue recognition on solar power systems, offset by increased revenue related to solar power products.

Concentrations: Sales outside the Americas Segment represented approximately 22% of total revenue recognized during the three months ended September 28, 2014 as compared with 33% of total revenue recognized during the three months ended September 29, 2013. The decrease in percentage of revenue outside the Americas Segment is primarily driven by lower revenue recognized within the EMEA region due to substantial completion of revenue recognition on certain utility-scale solar power systems. Sales outside the Americas Segment represented 29% of total revenue recognized during the nine months ended September 28, 2014 as compared with 31% of total revenue recognized during the nine months ended September 29, 2013. The decrease in percentage of revenue outside the Americas Segment is primarily driven by an increase in revenue within the Americas Segment, combined with a decline in revenue in the Middle East and Africa that was partially offset by an increase in component sales within the APAC Segment, primarily in Japan.

The table below represents our significant customers that accounted for greater than 10 percent of total revenue in each of the three and nine months ended September 28, 2014 and September 29, 2013, respectively.

Solar Power Products: Revenue related to solar power products decreased by 6% during the three months ended September 28, 2014 as compared to the three months ended September 29, 2013 primarily due to a decrease in direct sales made through our global dealer network, partially offset by an increase in component sales made under long-term supply agreements within the APAC region. Revenue related to solar power products increased by 6% during the nine months ended September 28, 2014 as compared to the nine months ended September 29, 2013 primarily due to additional component sales made under long-term supply agreements, within both the EMEA and APAC regions.

Solar Power Systems: Revenue related to our solar power systems increased 6% in the three months ended September 28, 2014 as compared to the three months ended September 29, 2013 due to additional revenue recognized on new construction and development contracts. Revenue related to our solar power systems decreased 5% in the nine months ended September 28, 2014 as compared to the nine months ended September 29, 2013 due to substantial completion of revenue recognition on certain large-scale solar power systems during the interim period, partially offset by additional revenue recognized on new construction and development contracts.

41

Residential Leases: Revenue recognized in connection with our residential lease program decreased 2% during the three months ended September 28, 2014 as compared to the three months ended September 29, 2013 primarily attributable to fewer leased solar power systems placed in service. Revenue recognized in connection with our residential lease program increased 7% in the nine months ended September 28, 2014 as compared to the nine months ended September 29, 2013 primarily attributable to additional leased solar power systems placed in service.

Americas Gross Margin: Gross margin for our Americas Segment decreased 11 percentage points during the three months ended September 28, 2014 as compared to the three months ended September 29, 2013, primarily as a result of a $25.6 million non-recurring gain in the third quarter of fiscal 2013 that was associated with the termination of a third-party supply contract. Gross margin increased 1 percentage point during the nine months ended September 28, 2014 as compared to the nine months ended September 29, 2013 as a result of favorable margins on large utility-scale solar power systems recognized in fiscal 2014, partially offset by the aforementioned non-recurring benefit in the 2013 period.

EMEA Gross Margin: Gross margin for our EMEA Segment decreased 20 percentage points during the three months ended September 28, 2014 as compared to the three months ended September 29, 2013, resulting in a negative margin, primarily due to reserves associated with VAT receivables and the termination of a third-party supply contract in the 2014 period. The decrease was also a result of a $9.4 million non-recurring gain in the third quarter of fiscal 2013 that was associated with the termination of a separate third-party supply contract. Gross margin for our EMEA Segment increased 13 percentage points during the nine months ended September 28, 2014 as compared to nine months ended September 29, 2013 as a result of more favorable margins on ongoing solar power projects, increased activity in component sales within the region, and recoveries in average selling prices, partially offset by the aforementioned non-recurring benefit in the 2013 period.

APAC Gross Margin: Gross margin for our APAC Segment decreased 32 percentage points during the three months ended September 28, 2014 as compared to the three months ended September 29, 2013 primarily as a result of a $17.0 million non-recurring gain in the third quarter of fiscal 2013 that was associated with the termination of a third-party supply contract. Gross margin for our APAC Segment decreased 14 percentage points during the nine months ended September 28, 2014 as compared to the nine months ended September 29, 2013 as a result of declines in average selling prices and an increase in the volume of components sold in the 2014 period, primarily in Japan, and also because of the aforementioned non-recurring benefit in the 2013 period.

Restructuring charges in the three and nine months ended September 28, 2014 and September 29, 2013 were minimal due to the substantial completion of activities associated with our restructuring plans approved in fiscal 2012 and 2011. We expect to continue to incur restructuring costs as we finalize previous estimates and actions in connection with these plans, primarily due to other costs, such as legal services.

See Note 6 of our Notes to Consolidated Financial Statements for further information regarding our restructuring plans.

As a percentage of revenue	1		%	1		%		—		%	—		%

In the three and nine months ended September 28, 2014, our income tax benefit of $8.3 million and $2.9 million, respectively, on an income before income taxes and equity in earnings of unconsolidated investees of $7.3 million and $53.2 million, respectively, was primarily due to an increase in forecasted profit before tax for the fiscal period, provision to return adjustments, and acquired deferred tax liabilities used to reduce the valuation allowance, partially offset by state taxes and the recognition of previously unrecognized tax benefits. In the three and nine months ended September 29, 2013, our income tax benefit of $4.6 million and income tax provision of $2.9 million, respectively, on an income before income taxes and equity in earnings of unconsolidated investees of $81.2 million and $30.3 million respectively, was primarily due to projected tax expense in profitable foreign jurisdictions as well as minimum taxes and the recognition of a previously unrecognized tax benefit.

A material amount of our total revenue is generated from customers located outside of the United States, and a substantial portion of our assets and employees are located outside of the United States. United States income taxes and foreign withholding taxes have not been provided on the undistributed earnings of our non-United States subsidiaries as such earnings are intended to be indefinitely reinvested in operations outside the United States to extent that such earnings have not been currently or previously subjected to taxation of the United States.

We record a valuation allowance to reduce our United States and French deferred tax assets to the amount that is more likely than not to be realized. In assessing the need for a valuation allowance, we consider historical levels of income, expectations and risks associated with the estimates of future taxable income and ongoing prudent and feasible tax planning strategies. In the event we determine that we would be able to realize additional deferred tax assets in the future in excess of the net recorded amount, or if we subsequently determine that realization of an amount previously recorded is unlikely, we would record an adjustment to the deferred tax asset valuation allowance, which would change income tax in the period of adjustment. As of September 28, 2014, we believe there is insufficient evidence to realize additional deferred tax assets in the near term.

In the three months ended September 28, 2014 our net income decreased $70.1 million as compared to the three months ended September 29, 2013. The decrease in net income was primarily driven by: (i) a $84.7 million decrease in gross margin, $52 million of which is attributable to a non-recurring gain that occurred the third quarter of fiscal 2013 that was associated with the termination of a third-party supply contract, and (ii) a $6.6 million increase in operating expenses. The decrease was partially offset by (i) a $3.7 million decrease in income taxes and (iii) a $17.4 million decrease in Other expense, net due to lower interest expense as a result of the expiration of the Liquidity Support Agreement during the first quarter of fiscal 2014.

In the nine months ended September 28, 2014 our net income increased $31.8 million as compared to the nine months ended September 29, 2013. The increase in net income was primarily driven by: (i) a $5.2 million increase in gross margin due to favorable margins on various large utility-scale solar power systems recognized coupled with an overall decrease in material and installation costs, and (ii) a $42.9 million decrease in Other expense, net due to lower interest expense primarily as a result of the expiration of the Liquidity Support Agreement during the first quarter of fiscal 2014, but was partially offset by (iii) a $25.3 million increase in operating expenses.

Information about other significant variances in our results of operations is described above.

Net Loss Attributable to Noncontrolling Interests and Redeemable Noncontrolling Interests

Net loss attributable to noncontrolling interests and redeemable noncontrolling interests	$	14,749	$	21,004	(30)%	$	49,693	$	43,577	14%

We have entered into facilities with third-party investors under which the parties invest in entities that hold SunPower solar power systems and leases with residential customers. We determined that we hold controlling interests in these less-than-wholly-owned entities and have fully consolidated these entities as a result. We apply the hypothetical liquidation value method in allocating recorded net income (loss) to each investor based on the change in the reporting period, of the amount of net assets of the entity to which each investor would be entitled to under the governing contractual arrangements in a liquidation scenario. In the three months ended September 28, 2014 and September 29, 2013, we attributed $14.7 million and $21.0 million, respectively, of losses to the third-party investors primarily as a result of allocating certain assets, including tax credits and accelerated tax depreciation benefits, to the investors. The $6.3 million decrease in loss attributable to these third-party investors is primarily the result of lower number of leases placed in service quarter over quarter.

In the nine months ended September 28, 2014 and September 29, 2013, we attributed $49.7 million and $43.6 million, respectively, of losses to the third-party investors primarily as a result of allocating certain assets, including tax credits and accelerated tax depreciation benefits, to the investors. The $6.1 million increase in loss attributable to these third-party investors is primarily the result of additional leases placed in service under existing and new facilities executed with third-party investors in the interim period.

Debt and Credit Sources

Convertible Debentures

As of September 28, 2014, an aggregate principal amount of $400.0 million of the 0.875% debentures due 2021 remain issued and outstanding. The 0.875% debentures due 2021 were issued on June 11, 2014. Interest on the 0.875% debentures due 2021 is payable on June 1 and December 1 of each year, beginning on December 1, 2014. Holders are able to exercise their right to convert the debentures at any time into shares of the Company's common stock at an initial conversion price approximately equal to $48.76 per share, subject to adjustment in certain circumstances. If not earlier repurchased or converted, the 0.875% debentures due 2021 mature on June 1, 2021. Holders may require us to repurchase all or a portion of their 0.875% debentures due 2021, upon a fundamental change, as described in the governing agreement, at a cash repurchase price equal to 100% of the principal amount plus accrued and unpaid interest. If we undergo a non-stock change of control fundamental change, as described in the governing agreement, the 0.875% debentures due 2021 will be subject to redemption at our option, in whole but not in part, for a period of 30 calendar days following a repurchase date relating to the non-stock change of control fundamental change, at a cash redemption price equal to 100% of the principal amount plus accrued and unpaid interest. In the event of certain events of default, Wells Fargo, the trustee, or the holders of a specified amount of then-outstanding 0.875% debentures due 2021 will have the right to declare all amounts then outstanding due and payable.

As of September 28, 2014, an aggregate principal amount of $300.0 million of the 0.75% debentures due 2018 remain issued and outstanding. The 0.75% debentures due 2018 were issued on May 29, 2013. Interest on the 0.75% debentures due 2018 is payable on June 1 and December 1 of each year. Holders are able to exercise their right to convert the debentures at any time into shares of our common stock at an initial conversion price equal to $24.95 per share. The applicable conversion rate may be subject to adjustment in certain circumstances. If not earlier converted, the 0.75% debentures due 2018 mature on June 1, 2018. Holders may require us to repurchase all or a portion of their 0.75% debentures due 2018, upon a fundamental change, as described in the governing agreement, at a cash repurchase price equal to 100% of the principal amount plus accrued and unpaid interest. If we undergo a non-stock change of control fundamental change, as described in the governing agreement, the 0.75% debentures due 2018 will be subject to redemption at our option, in whole but not in part, for a period of 30 calendar days following a repurchase date relating to the non-stock change of control fundamental change, at a cash redemption price equal to 100% of the principal amount plus accrued and unpaid interest. In the event of certain events of default, Wells Fargo, the trustee, or the holders of a specified amount of then-outstanding 0.75% debentures due 2018 will have the right to declare all amounts then outstanding due and payable.

As of September 28, 2014, an aggregate principal amount of $249.7 million of the 4.50% debentures due 2015 remain issued and outstanding. Interest on the 4.50% debentures is payable on March 15 and September 15 of each year. The 4.50% debentures mature on March 15, 2015. The 4.50% debentures are convertible only into cash, and not into shares of our common stock (or any other securities). Before December 15, 2014, if the weighted average price of our common stock is

48

more than 130% of the then current conversion price for at least 20 out of 30 consecutive trading days ending on the last trading day of the fiscal quarter, then holders of the 4.50% debentures due 2015 have the right to convert the debentures any day in the following fiscal quarter and, thereafter, they will be convertible at any time, based on an initial conversion price of $22.53 per share of our common stock. During the third quarter of fiscal 2014, the conversion right was triggered and the holders of the 4.50% debentures may exercise their right to convert the debentures any day during the fourth quarter of fiscal 2014. The conversion price will be subject to adjustment in certain events, such as distributions of dividends or stock splits. Upon conversion, we will deliver an amount of cash calculated by reference to the price of our common stock over the applicable observation period. We may not redeem the 4.50% debentures prior to maturity. Holders may also require us to repurchase all or a portion of their 4.50% debentures upon a fundamental change, as defined in the debenture agreement, at a cash repurchase price equal to 100% of the principal amount plus accrued and unpaid interest. In the event of certain events of default, such as our failure to make certain payments or perform or observe certain obligations thereunder, Wells Fargo, the trustee, or holders of a specified amount of then-outstanding 4.50% debentures will have the right to declare all amounts then outstanding due and payable. Concurrent with the issuance of the 4.50% debentures, we entered into privately negotiated convertible debenture hedge transactions and warrant transactions which represent a call spread overlay with respect to the 4.50% debentures (the "CSO2015"), assuming full performance of the counterparties and 4.50% Warrants strike prices in excess of the conversion price of the 4.50% debentures.  Please see "Risks Related to our Debt and Equity Securities: Conversion of our outstanding 0.75% debentures, 4.75% debentures, our warrants related to our outstanding 4.50% and 4.75% debentures, and future substantial issuances or dispositions of our common stock or other securities, could dilute ownership and earnings per share or cause the market price of our stock to decrease." in "Part I. Item 1A: Risk Factors" in our fiscal 2013 Form 10-K.

Mortgage Loan Agreement with IFC

On May 6, 2010, we entered into a mortgage loan agreement with IFC. Under the loan agreement, we borrowed $75.0 million and are required to repay the amount borrowed starting two years after the date of borrowing, in 10 equal semiannual installments over the following 5 years. We are required to pay interest of LIBOR plus 3% per annum on outstanding borrowings; a front-end fee of 1% on the principal amount of borrowings at the time of borrowing; and a commitment fee of 0.5% per annum on funds available for borrowing and not borrowed. We may prepay all or a part of the outstanding principal, subject to a 1% prepayment premium. We have pledged certain assets as collateral supporting repayment obligations.

As of September 28, 2014, we had $47.5 million outstanding under the mortgage loan agreement. Additionally, in accordance with the terms of the mortgage loan agreement, we are required to establish a debt service reserve account which shall contain the amount, as determined by IFC, equal to the aggregate principal and interest due on the next succeeding interest payment date after such date. As of September 28, 2014 we had restricted cash and cash equivalents of $9.2 million related to the IFC debt service reserve.

Loan Agreement with California Enterprise Development Authority ("CEDA")

On December 29, 2010, we borrowed from CEDA the proceeds of the $30.0 million aggregate principal amount of CEDA's tax-exempt Recovery Zone Facility Revenue Bonds (SunPower Corporation - Headquarters Project) Series 2010 (the "Bonds") maturing April 1, 2031 under a loan agreement with CEDA. Certain of our obligations under the loan agreement were contained in a promissory note dated December 29, 2010 issued by us to CEDA, which assigned the promissory note, along with all right, title and interest in the loan agreement, to Wells Fargo, as trustee, with respect to the Bonds for the benefit of the holders of the Bonds. The Bonds bear interest at a fixed-rate of 8.50% per annum. Additionally, in accordance with the terms of the loan agreement, we are required to keep all loan proceeds on deposit with Wells Fargo, the trustee, until funds are withdrawn by us for use in relation to the design and leasehold improvements of our new corporate headquarters in San Jose, California.

As of September 28, 2014 the $30.0 million aggregate principal amount of the Bonds was classified as "Long-term debt" in our Consolidated Balance Sheets.

July 2013 Revolving Credit Facility with Credit Agricole

On July 3, 2013, we entered into a revolving credit agreement with Credit Agricole, as administrative agent, and certain financial institutions ("the July 2013 revolving credit facility"), under which we may borrow up to $250.0 million. On August 26, 2014, the Company entered into an amendment to the revolving credit facility that extends, among other things, the maturity date of the facility from July 3, 2016 to August 26, 2019 (the "Maturity Date"). Amounts borrowed may be repaid and reborrowed until the Maturity Date. The revolving credit facility allows us to request increases to the available capacity of the revolving credit facility to an aggregate of $300.0 million, subject to the satisfaction of certain conditions. The revolving credit

49

facility includes representations, covenants, and events of default customary for financing transactions of this type. The revolving credit facility was entered into in conjunction with the delivery by Total S.A. of a guarantee of our obligations under the facility. On January 31, 2014, (i) our obligations under the revolving credit facility became secured by a pledge of certain accounts receivable and inventory, (ii) certain of our subsidiaries entered into guaranties of the revolving credit facility, and (iii) Total S.A.'s guarantee of our obligations under the revolving credit facility expired (collectively, the “Restructuring”).

We are required to pay interest on outstanding borrowings under the facility and fees of (a) with respect to any LIBOR rate loan, an amount ranging from 1.50% to 2.00% (depending on our leverage ratio from time to time) plus the LIBOR rate divided by a percentage equal to one minus the stated maximum rate of all reserves required to be maintained against “Eurocurrency liabilities” as specified in Regulation D; (b) with respect to any alternate base rate loan, an amount ranging from 0.50% to 1.00% (depending on our leverage ratio from time to time) plus the greater of (1) the prime rate, (2) the Federal Funds rate plus 0.50%, and (3) the one-month LIBOR rate plus 1%; and (c) a commitment fee ranging from 0.25% to 0.35% (depending on our leverage ratio from time to time) per annum on funds available for borrowing and not borrowed.

As of September 28, 2014, the Company had no outstanding borrowings under the revolving credit facility.

August 2011 Letter of Credit Facility with Deutsche Bank

On August 9, 2011, we entered into a letter of credit facility agreement with Deutsche Bank, as issuing bank and as administrative agent, and certain financial institutions. Payment of obligations under the letter of credit facility is guaranteed by Total S.A. pursuant to the Credit Support Agreement between us and Total S.A. The letter of credit facility provides for the issuance, upon our request, of letters of credit by the issuing banks thereunder in order to support certain of our obligations, in an aggregate amount not to exceed $878.0 million for the period from January 1, 2014 through December 31, 2014. Aggregate letter of credit amounts may be increased upon the agreement of the parties but, otherwise, may not exceed (i) $936.0 million for the period from January 1, 2015 through December 31, 2015, and (ii) $1.0 billion for the period from January 1, 2016 through June 28, 2016. Each letter of credit issued under the letter of credit facility must have an expiration date no later than the second anniversary of the issuance of that letter of credit, provided that up to 15% of the outstanding value of the letters of credit may have an expiration date of between two and three years from the date of issuance.

As of September 28, 2014, letters of credit issued under the August 2011 letter of credit facility with Deutsche Bank totaled $730.0 million.

September 2011 Letter of Credit Facility with Deutsche Bank and Deutsche Bank Trust Company Americas (together, "Deutsche Bank Trust")

On September 27, 2011, we entered into a letter of credit facility with Deutsche Bank Trust which provides for the issuance, upon request by us, letters of credit to support our obligations in an aggregate amount not to exceed $200.0 million. Each letter of credit issued under the facility is fully cash-collateralized and we have entered into a security agreement with Deutsche Bank Trust, granting them a security interest in a cash collateral account established for this purpose.

As of September 28, 2014 letters of credit issued under the Deutsche Bank Trust facility amounted to $1.2 million which were fully collateralized with restricted cash as classified on the Consolidated Balance Sheets.

Liquidity

As of September 28, 2014, we had unrestricted cash and cash equivalents of $922.7 million as compared to $762.5 million as of December 29, 2013. Our cash balances are held in numerous locations throughout the world and as of September 28, 2014, we had approximately $482.1 million held outside of the United States. This offshore cash is used to fund operations of our EMEA and APAC business units as well as non-U.S. manufacturing operations, which require local payment for product materials and other expenses.  The amounts held outside of the United States represent the earnings of our foreign subsidiaries which, if repatriated to the United States under current law, would be subject to United States federal and state tax less applicable foreign tax credits. Repatriation of earnings that have not been subjected to U.S. or foreign withholding tax and that have been indefinitely reinvested outside the U.S. could result in additional United States federal income tax or foreign withholding tax payments in future years.

50

On July 5, 2010, we formed our AUOSP joint venture. Under the terms of the joint venture agreement, we and AU Optronics Singapore Pte. Ltd. ("AUO") each own 50% of AUOSP. We are each obligated to provide additional funding to AUOSP in the future. Under the joint venture agreement, each shareholder agreed to contribute additional amounts to the joint venture through 2014 amounting to $241.0 million, or such lesser amount as the parties may mutually agree (see the Contractual Obligations table below). However, AUOSP's $300 million secured loan facility in connection with Fab 3A includes a covenant that requires the joint venture partners to make certain minimum equity injections in the beginning of fiscal 2015. See also "If we experience interruptions in the operation of our solar cell production lines, or we are not successful in operating our joint venture AUOSP, our revenue and results of operations may be materially and adversely affected." in "Part I. Item 1A: Risk Factors" in our fiscal 2013 Form 10-K. In addition, if AUOSP, or either shareholder requests additional equity financing to AUOSP, then the shareholders will each be required to make additional cash contributions of up to $50.0 million in the aggregate.

Our 4.50% debentures due 2015 are convertible into cash. Under the terms of the 4.50% Warrants, we sold to affiliates of certain of the initial purchasers of the 4.50% cash convertible debentures warrants to acquire, subject to anti-dilution adjustments, up to 11.1 million shares of our common stock. The bond hedge and warrants described in Note 9 of Notes to the Consolidated Financial Statements represent a call spread overlay with respect to the 4.50% debentures. Assuming full performance by the counterparties (and 4.50% Warrants strike prices in excess of the conversion price of the 4.50% debentures), the transactions effectively reduce our potential payout over the principal amount on the 4.50% debentures upon conversion of the 4.50% debentures.

We expect total capital expenditures related to purchases of property, plant and equipment in the range of $150 million to $170 million in fiscal 2014 in order to increase our manufacturing capacity, improve our current and next generation solar cell manufacturing technology, and other projects. In addition, we expect to invest a significant amount of capital to develop solar power systems and plants for sale to customers. The development of solar power plants can require long periods of time and substantial initial investments. Our efforts in this area may consist of all stages of development, including land acquisition, permitting, financing, construction, operation and the eventual sale of the projects. We often choose to bear the costs of such efforts prior to the final sale to a customer, which involves significant upfront investments of resources (including, for example, large transmission deposits or other payments, which may be non-refundable), land acquisition, permitting, legal and other costs, and in some cases the actual costs of constructing a project, in advance of the signing of PPAs and EPC contracts and the receipt of any revenue, much of which is not recognized for several additional months or years following contract signing. Any delays in disposition of one or more projects could have a negative impact on our liquidity.

Certain of our customers also require performance bonds issued by a bonding agency or letters of credit issued by financial institutions, which are returned to us upon satisfaction of contractual requirements. If there is a contractual dispute with the customer, the customer may withhold the security or make a draw under such security, which could have an adverse impact on our liquidity position. Obtaining letters of credit may require adequate collateral. All letters of credit issued under our August 2011 Deutsche Bank facility are guaranteed by Total S.A. pursuant to the Credit Support Agreement. Our letter of credit facility with Deutsche Bank Trust is fully collateralized by restricted cash, which reduces the amount of cash available for operations. As of September 28, 2014, letters of credit issued under the Deutsche Bank Trust facility amounted to $1.2 million which were fully collateralized with restricted cash on the Consolidated Balance Sheets.

In fiscal 2011, we launched our residential lease program with dealers in the United States, in partnership with a third-party financial institution, which allows customers to obtain SunPower systems under lease agreements up to 20 years, subject to financing availability. We have entered into facilities with financial institutions that will provide financing to support additional residential solar lease projects. Under the terms of certain programs we receive upfront payments for periods under which the third-party financial institution has agreed to assume collection risk for certain residential leases. Changes in the amount or timing of upfront payments received from the financial institutions may have an impact on our cash position within the next twelve months. The normal collection of monthly rent payments for leases placed in service is not expected to have a material impact on our cash position within the next twelve months. We have entered into facilities with third-party investors under which both parties will invest in entities which hold SunPower solar power systems and leases with residential customers. We were determined to hold a controlling interest in these less-than-wholly-owned entities and have fully consolidated these entities as a result (see Note 4 of Notes to the Consolidated Financial Statements). As of September 28, 2014, we have entered into a total of seven facilities with third-party investors and received $175.3 million in contributions from investors under the related facility agreements. We are actively arranging additional third-party financing for our residential lease program; however, due to the general challenging credit markets we may be unable to arrange additional financing partners for our residential lease program in future periods, which could have a negative impact on our sales. In the unlikely event that we enter into a material number of additional leases without promptly obtaining corresponding third-party financing, our cash and working capital could be negatively impacted.

51

We believe that our current cash, cash equivalents and cash expected to be generated from operations will be sufficient to meet our working capital and fund our committed capital expenditures over the next 12 months, including the development and construction of solar power systems and plants over the next 12 months, as well as repay our current indebtedness, including our 4.50% debentures due 2015 (described below). In addition, we have $250 million available to us under our revolving credit facility with Credit Agricole. However, there can be no assurance that our liquidity will be adequate over time. A significant portion of our revenue is generated from a limited number of customers and large projects and our inability to execute these projects, or to collect from these customers or for these projects, would have a significant negative impact on our business. Our capital expenditures and use of working capital may be greater than we expect if we decide to make additional investments in the development and construction of solar power plants and sales of power plants and associated cash proceeds are delayed, or if we decide to accelerate increases in our manufacturing capacity internally or through capital contributions to joint ventures. We require project financing in connection with the construction of solar power plants, which financing may not be available on terms acceptable to us. In addition, we could in the future make additional investments in our joint ventures or guarantee certain financial obligations of our joint ventures, which could reduce our cash flows, increase our indebtedness and expose us to the credit risk of our joint ventures. See also "A limited number of customers and large projects are expected to continue to comprise a significant portion of our revenues and any decrease in revenue from these customers or projects, payments of liquidated damages, or an increase in related expenses, could have a material adverse effect on our business, results of operations and financial condition,"and "We may be unable to generate sufficient cash flows or obtain access to external financing necessary to fund our operations and make adequate capital investments as planned due to the general economic environment and the continued market pressure driving down the average selling prices of our solar power products, among other factors." in Part I, Item 1A "Risk Factors" in our fiscal 2013 Form 10-K.

As of September 28, 2014, an aggregate principal amount of $249.7 million of our 4.50% debentures due 2015 remain issued and outstanding and are classified as short-term debt on our Consolidated Balance Sheet. We have $250.0 million available to us under our revolving credit facility with Credit Agricole and may request increases to the available capacity of the revolving credit facility to an aggregate of $300.0 million, subject to the satisfaction of certain conditions. Proceeds from our revolving credit facility with Credit Agricole may be used for general corporate purposes. There are no assurances that we will have sufficient available cash to repay such indebtedness or we will be able to refinance such indebtedness on similar terms to the expiring indebtedness. If our capital resources are insufficient to satisfy our liquidity requirements, we may seek to sell additional equity securities or debt securities or obtain other debt financing. The current economic environment, however, could limit our ability to raise capital by issuing new equity or debt securities on acceptable terms, and lenders may be unwilling to lend funds on acceptable terms that would be required to supplement cash flows to support operations. The sale of additional equity securities or convertible debt securities would result in additional dilution to our stockholders (and potential for further dilution upon the exercise of warrants or the conversion of convertible debt) and may not be available on favorable terms or at all, particularly in light of the current conditions in the financial and credit markets. Additional debt would result in increased expenses and would likely impose new restrictive covenants which may be similar or different than those restrictions contained in the covenants under our current loan agreements and debentures. In addition, financing arrangements, including project financing for our solar power plants and letters of credit facilities, may not be available to us, or may not be available in amounts or on terms acceptable to us.

¹  Convertible debt, including interest, relates to the aggregate of $949.8 million in outstanding principal amount of our senior convertible debentures on September 28, 2014. For the purpose of the table above, we assume that all holders of the outstanding debentures will hold the debentures through the date of maturity, and upon conversion, the values of the senior convertible debentures will be equal to the aggregate principal amount with no premiums.

²  IFC mortgage loan, including interest, relates to the $47.5 million borrowed as of September 28, 2014. Under the loan agreement, we are required to repay the amount borrowed, starting 2 years after the date of borrowing, in 10 equal semiannual installments over the following 5 years. We are required to pay interest of LIBOR plus 3% per annum on outstanding borrowings; a front-end fee of 1% on the principal amount of borrowings at the time of borrowing; and a commitment fee of 0.5% per annum on funds available for borrowing and not borrowed.

³  CEDA loan, including interest, relates to the proceeds of the $30.0 million aggregate principal amount of the Bonds. The Bonds mature on April 1, 2031 and bear interest at a fixed rate of 8.50% through maturity.

⁴  Other debt, including interest, primarily relates to non-recourse to finance projects and solar power systems and leases under our residential lease program as described in Note 9 of Notes to the Consolidated Financial Statements.

⁵  We and AUO agreed in the joint venture agreement to contribute additional amounts to AUOSP through 2014 amounting to $241.0 million by each shareholder, or such lesser amount as the parties may mutually agree. Further, in connection with a purchase agreement with a non-public company we will be required to provide additional financing to such party of up to $2.9 million, subject to certain conditions.

⁶  Operating lease commitments primarily relate to certain solar power systems leased from unaffiliated third parties over minimum lease terms of up to 20 years and various facility lease agreements.

⁷  Sale-leaseback financing relates to future minimum lease obligations for solar power systems under sale-leaseback arrangements which were determined to include integral equipment and accounted for under the financing method.

⁸  Capital lease commitments primarily relate to certain buildings, manufacturing and equipment under capital leases in Europe for terms of up to 12 years.

⁹  Non-cancellable purchase orders relate to purchases of raw materials for inventory and manufacturing equipment from a variety of vendors.

¹⁰  Purchase commitments under agreements relate to arrangements entered into with several suppliers, including joint ventures, for polysilicon, ingots, wafers, and Solar Renewable Energy Credits, among others. These agreements specify future quantities and pricing of products to be supplied by the vendors for periods up to 10 years and there are certain consequences, such as forfeiture of advanced deposits and liquidated damages relating to previous purchases, in the event that we terminate the arrangements.

53

Liabilities Associated with Uncertain Tax Positions

Due to the complexity and uncertainty associated with our tax positions, we cannot make a reasonably reliable estimate of the period in which cash settlement will be made for our liabilities associated with uncertain tax positions in other long-term liabilities. Therefore, they have been excluded from the table above. As of September 28, 2014, total liabilities associated with uncertain tax positions were $27.1 million and are included in "Other long-term liabilities" in our Consolidated Balance Sheets as they are not expected to be paid within the next twelve months.

Off-Balance-Sheet Arrangements

As of September 28, 2014, we did not have any significant off-balance-sheet arrangements, as defined in Item 303(a)(4)(ii) of SEC Regulation S-K.

54

ITEM 3: QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

Foreign Currency Exchange Risk

Our exposure to movements in foreign currency exchange rates is primarily related to sales to European customers that are denominated in Euros. Revenue generated from European customers represented 7% and 13% of our total revenue in the three and nine months ended September 28, 2014, respectively, and 18% and 16% of our total revenue in the three and nine months ended September 29, 2013, respectively. A 10% change in the Euro exchange rate would have impacted our revenue by approximately $4.5 million and $23.6 million for the three and nine months ended September 28, 2014, respectively, and $12.1 million and $29.6 million in the three and nine months ended September 29, 2013, respectively.

In the past, we have experienced an adverse impact on our revenue, gross margin and profitability as a result of foreign currency fluctuations. When foreign currencies appreciate against the U.S. dollar, inventories and expenses denominated in foreign currencies become more expensive. Strengthening of the Malaysian Ringgit against the U.S. dollar would increase AUOSP's liability under the facility agreement with the Malaysian government which in turn would negatively impact our equity in earnings (loss) of the unconsolidated investee. An increase in the value of the U.S. dollar relative to foreign currencies could make our solar power products more expensive for international customers, thus potentially leading to a reduction in demand, our sales and profitability. Furthermore, many of our competitors are foreign companies that could benefit from such a currency fluctuation, making it more difficult for us to compete with those companies.

We currently conduct hedging activities which involve the use of option and forward currency contracts that are designed to address our exposure to changes in the foreign exchange rate between the U.S. dollar and other currencies. As of September 28, 2014, we had outstanding hedge option currency contracts and forward currency contracts with aggregate notional values of $46.6 million and $72.2 million respectively. As of December 29, 2013, we held option and forward contracts totaling $115.3 million and $75.0 million, respectively, in notional value. Because we hedge some of our expected future foreign exchange exposure, if associated revenues do not materialize we could experience a reclassification of ineffective gains or losses into earnings. Such a reclassification could adversely impact our revenue, margins and results of operations. We cannot predict the impact of future exchange rate fluctuations on our business and operating results.

Credit Risk

We have certain financial and derivative instruments that subject us to credit risk. These consist primarily of cash and cash equivalents, restricted cash and cash equivalents, investments, accounts receivable, notes receivable, advances to suppliers, foreign currency option contracts, foreign currency forward contracts, bond hedge and warrant transactions. We are exposed to credit losses in the event of nonperformance by the counterparties to our financial and derivative instruments. Our investment policy requires cash and cash equivalents, restricted cash and cash equivalents, and investments to be placed with high-quality financial institutions and limits the amount of credit risk from any one issuer. We additionally perform ongoing credit evaluations of our customers’ financial condition whenever deemed necessary and generally do not require collateral.

We enter into agreements with vendors that specify future quantities and pricing of polysilicon to be supplied for periods up to 10 years. Under certain agreements, we are required to make prepayments to the vendors over the terms of the arrangements. As of September 28, 2014 and December 29, 2013, advances to suppliers totaled $401.9 million and $383.3 million, respectively. Two suppliers accounted for 82% and 18% of total advances to suppliers as of September 28, 2014, and 77% and 22% as of December 29, 2013. As of September 28, 2014, the Company has future prepayment obligations through fiscal 2014 totaling $16.4 million.

We enter into foreign currency derivative contracts and convertible debenture hedge transactions with high-quality financial institutions and limit the amount of credit exposure to any single counterparty. The foreign currency derivative contracts are limited to a time period of 15 months or less. We regularly evaluate the credit standing of our counterparty financial institutions.

Interest Rate Risk

We are exposed to interest rate risk because many of our customers depend on debt financing to purchase our solar power systems. An increase in interest rates could make it difficult for our customers to obtain the financing necessary to purchase our solar power systems on favorable terms, or at all, and thus lower demand for our solar power products, reduce revenue and adversely impact our operating results. An increase in interest rates could lower a customer's return on investment in a system or make alternative investments more attractive relative to solar power systems, which, in each case, could cause our customers to seek alternative investments that promise higher returns or demand higher returns from our solar power systems, reduce gross margin and adversely impact our operating results. This risk is significant to our business because our

55

sales model is highly sensitive to interest rate fluctuations and the availability of credit, and would be adversely affected by increases in interest rates or liquidity constraints.

Our interest expense would increase to the extent interest rates rise in connection with our variable interest rate borrowings. As of September 28, 2014, the outstanding principal balance of our variable interest borrowings was $47.5 million. We do not believe that an immediate 10% increase in interest rates would have a material effect on our financial statements. In addition, lower interest rates have an adverse impact on our interest income. Our investment portfolio primarily consists of $463.0 million in money market funds as of September 28, 2014 which exposes us to interest rate risk. Due to the relatively short-term nature of our investment portfolio, we do not believe that an immediate 10% increase in interest rates would have a material effect on the fair market value of our money market funds. Since we believe we have the ability to liquidate substantially all of this portfolio, we do not expect our operating results or cash flows to be materially affected to any significant degree by a sudden change in market interest rates on our investment portfolio.

Equity Price Risk involving Minority Investments in Joint Ventures and Other Non-Public Companies

Our investments held in joint ventures and other non-public companies expose us to equity price risk. As of September 28, 2014 and December 29, 2013, investments of $137.1 million and $131.7 million, respectively, are accounted for using the equity method, and $17.3 million and $12.4 million, respectively, are accounted for using the cost method. These strategic investments in third parties are subject to risk of changes in market value, which if determined to be other-than-temporary, could result in realized impairment losses. We generally do not attempt to reduce or eliminate our market exposure in equity and cost method investments. We monitor these investments for impairment and record reductions in the carrying values when necessary. Circumstances that indicate an other-than-temporary decline include the valuation ascribed to the issuing company in subsequent financing rounds, decreases in quoted market prices and declines in operations of the issuer. There can be no assurance that our equity and cost method investments will not face risks of loss in the future.

Interest Rate Risk and Market Price Risk Involving Convertible Debt

The fair market value of our outstanding convertible debentures is subject to interest rate risk, market price risk and other factors due to the convertible feature of the debentures. The fair market value of the debentures will generally increase as interest rates fall and decrease as interest rates rise. In addition, the fair market value of the debentures will generally increase as the market price of our common stock increases and decrease as the market price of our common stock falls. The interest and market value changes affect the fair market value of the debentures, but do not impact our financial position, cash flows or results of operations due to the fixed nature of the debt obligations, except to the extent increases in the value of our common stock may provide the holders of our 4.50% debentures due 2015, and/or 0.75% debentures due 2027 the right to convert such debentures into cash in certain instances. The aggregate estimated fair value of our outstanding convertible debentures was $1,322.8 million as of September 28, 2014. The aggregate estimated fair value of our outstanding convertible debentures was $980.8 million as of December 29, 2013. Estimated fair values are based on quoted market prices as reported by an independent pricing source. A 10% increase in quoted market prices would increase the estimated fair value of our then-outstanding debentures to $1,455.0 million and $1,078.9 million as of September 28, 2014 and December 29, 2013, respectively, and a 10% decrease in the quoted market prices would decrease the estimated fair value of our then-outstanding debentures to $1,190.5 million and $882.7 million as of September 28, 2014 and December 29, 2013, respectively.

ITEM 4:CONTROLSAND PROCEDURES

Evaluation of Disclosure Controls and Procedures

We maintain "disclosure controls and procedures," as defined in Rule 13a-15(e) and 15d-15(e) under the Exchange Act, that are designed to provide reasonable assurance that information required to be disclosed in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. In designing and evaluating our disclosure controls and procedures, management recognizes that disclosure controls and procedures, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the disclosure controls and procedures are met. Additionally, in designing disclosure controls and procedures, our management is required to apply its judgment in evaluating the cost-benefit relationship of possible disclosure controls and procedures. The design of any disclosure control and procedure also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions.

Based on their evaluation as of the end of the period covered by this Quarterly Report on Form 10-Q, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were effective as of September 28, 2014 at a reasonable assurance level.

Changes in Internal Control over Financial Reporting

We regularly review our system of internal control over financial reporting and make changes to our processes and systems to improve controls and increase efficiency, while ensuring that we maintain an effective internal control environment. Changes may include such activities as implementing new, more efficient systems, consolidating activities, and migrating processes.

There were no changes in our internal control over financial reporting that occurred during our most recent fiscal quarter that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II

ITEM 1. LEGAL PROCEEDINGS

The disclosure under "Legal Matters" in "Note 7. Commitments and Contingencies" in "Part I. Financial Information, Item 1. Financial Statements: Notes to Condensed Consolidated Financial Statements" of this Quarterly Report on Form 10-Q is incorporated herein by reference.

ITEM 1A. RISK FACTORS

In addition to other information set forth in this report, readers should carefully consider the risk factors discussed in "Part I. Item 1A: Risk Factors" in our Annual Report on Form 10-K for the fiscal year ended December 29, 2013, which could materially affect our business, financial condition or future results. The risks described in our Annual Report on Form 10-K are not the only risks facing our company. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition or future results, as could the following:

The execution of our growth strategy is dependent upon the continued availability of third-party financing arrangements for our solar power plants, our residential lease program and our customers, and is affected by general economic conditions.

Global economic conditions and the limited availability of credit and liquidity could materially and adversely affect our business and results of operations. We often require project financing for development and construction of our solar power plant projects, which require significant investments before the equity is later sold to investors. Many purchasers of our systems projects have entered into third-party arrangements to finance their systems over an extended period of time, while many end- customers have chosen to purchase solar electricity under a PPA with an investor or financing company that purchases the system from us or our authorized dealers. In addition, under our power purchase business model, we often execute PPAs directly with the end-user, with the expectation that we will later assign the PPA to a financier. Under such arrangements, the financier separately contracts with us to acquire and build the solar power system, and then sells the electricity to the end-user under the assigned PPA. When executing PPAs with end-users, we seek to mitigate the risk that financing will not be available

57

for the project by allowing termination of the PPA in such event without penalty. However, we may not always be successful in negotiating for penalty-free termination rights for failure to obtain financing, and certain end-users have required substantial financial penalties in exchange for such rights. These structured finance arrangements are complex and may not be feasible in many situations.

Due to challenging credit markets, we may be unable to obtain project financing for our projects, customers may be unable or unwilling to finance the cost of our products, we may have difficulties in reaching agreements with financiers to finance the construction of our solar power systems, or the parties that have historically provided this financing may cease to do so, or only do so on terms that are substantially less favorable for us or our customers, any of which could materially and adversely affect our revenue and growth in all segments of our business. Our plans to continue to grow our residential lease program may be delayed if credit conditions prevent us from obtaining or maintaining arrangements to finance the program. We are actively arranging additional third-party financing for our residential lease program; however, due to the challenging credit markets, we may be unable to arrange additional financing partners for our residential lease program in future periods, which could have a negative impact on our sales. In the event we enter into a material number of additional leases without obtaining corresponding third-party financing, our cash, working capital and financial results could be negatively impacted. In addition, in the United States, with the expiration of the Treasury Grant under Section 1603 of the American Recovery and Reinvestment Act program, we will need to identify in the near term interested financiers with sufficient taxable income to monetize the tax incentives created by our solar systems. In the long term, as we look towards incentive-less markets, we will continue to need to identify financiers willing to finance residential solar systems. The lack of project financing could delay the development and construction of our solar power plant projects, thus reducing our revenues from the sale of such projects. If economic recovery is slow in the United States or elsewhere we may experience decreases in the demand for our solar power products, which may harm our operating results. We may in some cases seek to pursue partnership arrangements with financing entities to assist residential and other customers to obtain financing for the purchase or lease of our systems, which would expose us to credit or other risks. In addition, a rise in interest rates would likely increase our customers' cost of financing or leasing our products and could reduce their profits and expected returns on investment in our products. The general reduction in available credit to would-be borrowers or lessees, the poor state of economies worldwide, and the condition of worldwide housing markets could delay or reduce our sales of products to new homebuilders and authorized resellers.

Finally, in addition to the financing structures described above, we continue to assess the attractiveness and viability of alternative financing arrangements, including structures whereby we would seek to maximize the value of a select group of our project assets by maintaining ownership in them for a longer period of time and monetizing them through, among other strategies, the sale of equity interests in an entity - commonly referred to as a “HoldCo” or “YieldCo” - created for purposes of holding or acquiring such assets. We believe that the viability of a HoldCo or YieldCo, or similar structure would depend on our ability to develop revenue-generating solar assets, which is subject to the same project-level financing and operational risks described above, elsewhere in this Quarterly Report on Form 10-Q, and in our Annual Report in Form 10-K for the fiscal year ended December 29, 2013. Additionally, retaining ownership of solar assets for a longer period of time may adversely affect our results of operations in the short term and introduces the risk that the value of such assets will fluctuate over time because of, among other things, general market conditions, changes in the regulatory or public policy environment that affect the value of solar assets, changes in the prices of traditional energy, and the long-term success of our solar projects. If, in connection with pursuing new financing structures, we retain ownership of a larger portion of our project assets for a longer period of time, and if the value of such assets were to decline unexpectedly, we may not be able to generate returns on such assets that support the financing used to develop or maintain them, or we may be forced to sell the assets at a loss, either of which would have a material, adverse effect on our business, results of operations and financial condition.

We may utilize construction loans, term loans, sale-leaseback, preferred equity and other financing structures to fund acquisition, development, construction and expansion of photovoltaic power plant projects in the future, and such funds may or may not be available to further our plans. Furthermore, such project financing could increase our consolidated debt and may be structurally senior to other debt such as our Credit Agricole revolving credit facility and outstanding convertible debentures.

We have utilized or may utilize in the future project financing, including senior secured and unsecured indebtedness, construction financing, project financing, term loans and lease obligations. However, market conditions and other factors may prevent us from completing such financings in the future, which would limit our ability to acquire, develop, construct, or expand photovoltaic power plant projects on terms satisfactory to us, or at all. If we are unable to obtain financing on satisfactory terms, our plans and results of operations may be materially and adversely affected.

58

Certain of our subsidiaries and other affiliates are separate and distinct legal entities and, except in limited circumstances, have no obligation to pay any amounts due with respect to our indebtedness or indebtedness of other subsidiaries or affiliates, and do not guarantee the payment of interest on or principal of such indebtedness. Any such subsidiary financing would be added to our current consolidated debt levels and would likely be structurally senior to our corporate debt. In the event of a default under a project financing which we do not cure, the lenders or lessors would generally have rights to the power plant project and related assets. In the event of foreclosure after a default, we may not be able to retain any interest in the power plant project or other collateral supporting such financing. In addition, any such default or foreclosure may trigger cross default provisions in our other financing agreements, including our corporate debt obligations, which could materially and adversely affect our results of operations. In the event of our bankruptcy, liquidation or reorganization (or the bankruptcy, liquidation or reorganization of a subsidiary or affiliate), such subsidiaries’ or other affiliates’ creditors, including trade creditors and holders of debt issued by such subsidiaries or affiliates, will generally be entitled to payment of their claims from the assets of those subsidiaries or affiliates before any assets are made available for distribution to us or the holders of our indebtedness. As a result, holders of our corporate indebtedness will be effectively subordinated to all present and future debts and other liabilities (including trade payables) of certain of our subsidiaries. As of September 28, 2014, our subsidiaries had approximately $148.2 million in subsidiary project financing, which is effectively senior to our corporate debt, such as our Credit Agricole revolving credit facility, our 0.875% debentures due 2021, our 0.75% debentures due 2018, our 4.5% debentures due 2015, and our 0.75% debentures due 2027.

Note 2. TRANSACTIONS WITH TOTAL AND TOTAL S.A.

In June 2011, Total completed a cash tender offer to acquire 60% of the Company's then outstanding shares of common stock at a price of $23.25 per share, for a total cost of approximately $1.4 billion. In December 2011, the Company entered into a Private Placement Agreement with Total, under which Total purchased, and the Company issued and sold, 18.6 million shares of the Company's common stock for a purchase price of $8.80 per share, thereby increasing Total's ownership to approximately 66% of the Company's outstanding common stock as of that date.

Credit Support Agreement

In fiscal 2011, the Company and Total S.A. entered into a Credit Support Agreement (the "Credit Support Agreement") under which Total S.A. agreed to enter into one or more guarantee agreements (each a "Guaranty") with banks providing letter of credit facilities to the Company. Total S.A. will guarantee the Company's obligation to reimburse the applicable issuing bank a draw on a letter of credit and pay interest thereon in accordance with the letter of credit facility between such bank and the Company. Under the Credit Support Agreement, the Company may also request that Total S.A. provide a Guaranty in support of the Company's payment obligations with respect to a letter of credit facility. The Company is required to pay Total S.A. a guarantee fee for each letter of credit that is the subject of a Guaranty under the Credit Support Agreement and was outstanding for all or part of the preceding calendar quarter.

The Credit Support Agreement will terminate following the fifth anniversary of the CSA Effective Date, after the later of the payment in full of all obligations thereunder and the termination or expiration of each Guaranty provided thereunder.

Affiliation Agreement

The Company and Total have entered into an Affiliation Agreement that governs the relationship between Total and the Company (the "Affiliation Agreement"). Until the expiration of a standstill period (the "Standstill Period"), and subject to certain exceptions, Total, Total S.A., any of their respective affiliates and certain other related parties (the "Total Group") may not effect, seek, or enter into discussions with any third-party regarding any transaction that would result in the Total Group beneficially owning shares of the Company in excess of certain thresholds, or request the Company or the Company's independent directors, officers or employees, to amend or waive any of the standstill restrictions applicable to the Total Group.

The Affiliation Agreement imposes certain limitations on the Total Group's ability to seek to effect a tender offer or merger to acquire 100% of the outstanding voting power of the Company and imposes certain limitations on the Total Group's ability to transfer 40% or more of outstanding shares or voting power of the Company to a single person or group that is not a direct or indirect subsidiary of Total S.A. During the Standstill Period, no member of the Total Group may, among other things, solicit proxies or become a participant in an election contest relating to the election of directors to the Company's Board of Directors.

The Affiliation Agreement provides Total with the right to maintain its percentage ownership in connection with any new securities issued by the Company, and Total may also purchase shares on the open market or in private transactions with disinterested stockholders, subject in each case to certain restrictions.

The Affiliation Agreement also imposes certain restrictions with respect to the Company's and its Board of Directors' ability to take certain actions, including specifying certain actions that require approval by the directors other than the directors appointed by Total and other actions that require stockholder approval by Total.

Research & Collaboration Agreement

Total and the Company have entered into a Research & Collaboration Agreement (the "R&D Agreement") that establishes a framework under which the parties engage in long-term research and development collaboration ("R&D Collaboration"). The R&D Collaboration encompasses a number of different projects, with a focus on advancing the Company's technology position in the crystalline silicon domain, as well as ensuring the Company's industrial competitiveness. The R&D Agreement enables a joint committee to identify, plan and manage the R&D Collaboration.

Liquidity Support Agreement with Total S.A.

The Company was party to an agreement with a customer to construct the California Valley Solar Ranch, a solar park. Part of the debt financing necessary for the customer to pay for the construction of this solar park was provided by the Federal Financing Bank in reliance on a guarantee of repayment provided by the Department of Energy (the "DOE") under a loan guarantee program. In February 2012, the Company entered into a Liquidity Support Agreement with Total S.A. and the DOE, and a series of related agreements with Total S.A. and Total, under which Total S.A. agreed to provide the Company, or cause to be provided, additional liquidity under certain circumstances to a maximum amount of $600.0 million ("Liquidity Support Facility").  The Liquidity Support Facility was available until the completion of the solar park, which was completed in accordance with the terms of the relevant agreement in March 2014. Upon completion, the Liquidity Support Agreement was terminated. There were no outstanding guarantees or debt under the facility upon termination.

Compensation and Funding Agreement

In February 2012, the Company entered into a Compensation and Funding Agreement (the "Compensation and Funding Agreement") with Total S.A. which established the parameters for the terms of liquidity injections that may be required to be provided by Total S.A. to the Company from time to time. During the term of the Compensation and Funding Agreement, the Company is required to pay Total S.A. a guarantee fee in an amount equal to 2.75% per annum of the average amount of the Company's indebtedness that is guaranteed by Total S.A. pursuant to any guaranty issued in accordance with the terms of the Compensation and Funding Agreement during such quarter. Any payment obligations of the Company to Total S.A. under the Compensation and Funding Agreement that are not paid when due accrue interest until paid in full at a rate equal to 6-month U.S. LIBOR as in effect from time to time plus 5.00% per annum.

Upfront Warrant

In February 2012, the Company issued a warrant (the "Upfront Warrant") to Total S.A. to purchase 9,531,677 shares of the Company's common stock with an exercise price of $7.8685, subject to adjustment for customary anti-dilution and other events. The Upfront Warrant, governed by the Private Placement Agreement and the Compensation and Funding Agreement, is exercisable at any time for seven years after its issuance, provided that, so long as at least $25.0 million in aggregate of the Company's convertible debt remains outstanding, such exercise will not cause "any person," including Total S.A., to, directly or indirectly, including through one or more wholly-owned subsidiaries, become the "beneficial owner" (as such terms are defined in Rule 13d-3 and Rule 13d-5 under the Securities and Exchange Act of 1934, as amended), of more than 74.99% of the voting power of the Company's common stock at such time, a circumstance which would trigger the repurchase or conversion of the Company's existing convertible debt.

0.75% Debentures Due 2018

In May 2013, the Company issued $300.0 million in principal amount of its 0.75% senior convertible debentures due 2018 (the "0.75% debentures due 2018"). $200.0 million in aggregate principal amount of the 0.75% debentures due 2018 were acquired by Total. The 0.75% debentures due 2018 are convertible into shares of the Company's common stock at any time based on an initial conversion price equal to $24.95 per share, which provides Total the right to acquire up to 8,017,420 shares of the Company's common stock. The applicable conversion rate may adjust in certain circumstances, including a fundamental change, as described in the indenture governing the 0.75% debentures due 2018 (see Note 9).

0.875% Debentures Due 2021

In June 2014, the Company issued $400.0 million in principal amount of its 0.875% senior convertible debentures due 2021 (the "0.875% debentures due 2021"). An aggregate principal amount of $250.0 million of the 0.875% debentures due 2021 were acquired by Total. The 0.875% debentures due 2021 are convertible into shares of the Company's common stock at any time based on an initial conversion price equal to $48.76 per share, which provides Total the right to acquire up to 5,126,775 shares of the Company's common stock. The applicable conversion rate may adjust in certain circumstances, including a fundamental change, as described in the indenture governing the 0.875% debentures due 2021 (see Note 9).

Joint Projects with Total and its Affiliates:

The Company enters into various engineering, procurement and construction ("EPC") and operations and maintenance ("O&M") agreements relating to solar projects, including EPC and O&M services agreements relating to projects owned or partially owned by Total and its affiliates. As of September 28, 2014, the Company had $34.3 million of "Costs and estimated earnings in excess of billings" and $38.8 million of "Accounts receivable, net" on its Consolidated Balance Sheets related to projects in which Total and its affiliates have a direct or indirect material interest.

The Company and Summary of Significant Accounting Policies

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Significant Accounting Policies [Text Block]

THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The Company

SunPower Corporation (together with its subsidiaries, the "Company" or "SunPower") is a vertically integrated solar products and solutions company that designs, manufactures and delivers high-performance solar systems worldwide, serving as a one-stop shop for residential, commercial, and utility-scale power plant customers. SunPower Corporation is a majority owned subsidiary of Total Energies Nouvelles Activités USA("Total"), a subsidiary of Total S.A. ("Total S.A.") (see Note 2).

Basis of Presentation and Preparation

Principles of Consolidation

The consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America ("United States" or "U.S.") and include the accounts of the Company, all of its subsidiaries and special purpose entities, as appropriate under consolidation accounting guidelines. Intercompany transactions and balances have been eliminated in consolidation. The assets of the special purpose entities that the Company sets up related to project financing for customers are not designed to be available to service the general liabilities and obligations of the Company in certain circumstances.

Reclassifications

Certain prior period balances have been reclassified to conform to the current period presentation in the Company's consolidated financial statements and the accompanying notes. Such reclassifications had no effect on previously reported results of operations or accumulated deficit.

Fiscal Years

The Company has a 52-to-53-week fiscal year that ends on the Sunday closest to December 31. Accordingly, every fifth or sixth year will be a 53-week fiscal year. Both fiscal 2014 and 2013 are 52-week fiscal years. The third quarter of fiscal 2014 ended on September 28, 2014, while the third quarter of fiscal 2013 ended on September 29, 2013. The third quarters of fiscal 2014 and fiscal 2013 were both 13-week quarters.

Management Estimates

The preparation of the consolidated financial statements in conformity with U.S. generally accepted accounting principles ("U.S. GAAP") requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Significant estimates in these consolidated financial statements include percentage-of-completion for construction projects; allowances for doubtful accounts receivable and sales returns; inventory and project asset write-downs; stock-based compensation; estimates for future cash flows and economic useful lives of property, plant and equipment and other long-term assets; the fair value and residual value of leased solar power systems; fair value of financial instruments; valuation of certain accrued liabilities such as accrued warranty; and income taxes and tax valuation allowances. Actual results could materially differ from those estimates.

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board ("FASB") issued a new revenue recognition standard based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. The new revenue recognition standard becomes effective for the Company in the first quarter of fiscal 2017 and is to be applied retrospectively using one of two prescribed methods. The Company is evaluating the application method and impact on its consolidated financial statements and disclosures.

In July 2013, the FASB amended its guidance related to the presentation of unrecognized tax benefits. The amended guidance specifies when an unrecognized tax benefit or a portion of an unrecognized tax benefit should be presented as a liability versus an offset against a deferred tax asset when a net operating loss carryforward, a similar tax loss or tax credit carryforward exists. The amendment became effective for the Company in the first quarter of fiscal 2014 and did not have a material impact on its consolidated financial statements.

In March 2013, the FASB and International Accounting Standards Board ("IASB") issued common disclosure requirements that are intended to enhance comparability between financial statements prepared in accordance with U.S. GAAP and those prepared in accordance with International Financial Reporting Standards ("IFRS"). This new guidance is applicable to companies that have financial instruments or derivatives that are either offset in the balance sheet (presented on a net basis) or subject to an enforceable master netting arrangement or similar arrangement. The requirement does not change the existing offsetting eligibility criteria or the permitted balance sheet presentation for those instruments that meet the eligibility criteria. However, once this disclosure requirement becomes effective, companies will also be required to disclose information about financial instruments and derivatives instruments that have been offset and related arrangements and to provide both net (offset amounts) and gross information in the notes to the financial statements for relevant assets and liabilities that are offset. The disclosure requirement became effective retrospectively in the first quarter of the Company's fiscal year 2014 and did not have a material impact on the Company's consolidated financial statements as the requirement is disclosure-based only.

In March 2013, the FASB amended its guidance related to foreign currency matters requiring the release of the cumulative translation adjustment into net income when an entity ceases to have a controlling financial interest in a subsidiary or a group of assets within a foreign entity. The amendment became effective for the Company in the first quarter of fiscal 2014 and did not have a material impact on its consolidated financial statements.

Other than as described above, there has been no issued accounting guidance not yet adopted by the Company that it believes is material or potentially material to its consolidated financial statements.

The Company and Summary of Significant Accounting Policies (Policies)

9 Months Ended

Sep. 28, 2014

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Consolidation, Policy [Policy Text Block]

Principles of Consolidation

The consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America ("United States" or "U.S.") and include the accounts of the Company, all of its subsidiaries and special purpose entities, as appropriate under consolidation accounting guidelines. Intercompany transactions and balances have been eliminated in consolidation. The assets of the special purpose entities that the Company sets up related to project financing for customers are not designed to be available to service the general liabilities and obligations of the Company in certain circumstances.

Reclassification, Policy [Policy Text Block]

Reclassifications

Certain prior period balances have been reclassified to conform to the current period presentation in the Company's consolidated financial statements and the accompanying notes. Such reclassifications had no effect on previously reported results of operations or accumulated deficit.

Fiscal Period, Policy [Policy Text Block]

Fiscal Years

The Company has a 52-to-53-week fiscal year that ends on the Sunday closest to December 31. Accordingly, every fifth or sixth year will be a 53-week fiscal year. Both fiscal 2014 and 2013 are 52-week fiscal years. The third quarter of fiscal 2014 ended on September 28, 2014, while the third quarter of fiscal 2013 ended on September 29, 2013. The third quarters of fiscal 2014 and fiscal 2013 were both 13-week quarters.

Use of Estimates, Policy [Policy Text Block]

Management Estimates

The preparation of the consolidated financial statements in conformity with U.S. generally accepted accounting principles ("U.S. GAAP") requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Significant estimates in these consolidated financial statements include percentage-of-completion for construction projects; allowances for doubtful accounts receivable and sales returns; inventory and project asset write-downs; stock-based compensation; estimates for future cash flows and economic useful lives of property, plant and equipment and other long-term assets; the fair value and residual value of leased solar power systems; fair value of financial instruments; valuation of certain accrued liabilities such as accrued warranty; and income taxes and tax valuation allowances. Actual results could materially differ from those estimates.

Foreign Currency Exchange Risk

Designated Derivatives Hedging Cash Flow Exposure

The Company's cash flow exposure primarily relates to anticipated third-party foreign currency revenues and expenses. To protect financial performance, the Company enters into foreign currency forward and option contracts designated as cash flow hedges to hedge certain forecasted revenue transactions denominated in currencies other than their functional currencies.

As of September 28, 2014, the Company had designated outstanding cash flow hedge option contracts and forward contracts with an aggregate notional value of $46.6 million and $19.1 million, respectively. As of December 29, 2013, the Company had designated outstanding cash flow hedge option contracts and forward contracts with an aggregate notional value of $105.9 million and $42.8 million, respectively. The Company designates either gross external or intercompany revenue up to its net economic exposure. These derivatives have a maturity of 12 months or less and consist of foreign currency option and forward contracts. The effective portion of these cash flow hedges is reclassified into revenue when third-party revenue is recognized in the Consolidated Statements of Operations.

Non-Designated Derivatives Hedging Transaction Exposure

Derivatives not designated as hedging instruments consist of forward and option contracts used to hedge re-measurement of foreign currency denominated monetary assets and liabilities primarily for intercompany transactions, receivables from customers, and payables to third parties. Changes in exchange rates between the Company's subsidiaries' functional currencies and the currencies in which these assets and liabilities are denominated can create fluctuations in the Company's reported consolidated financial position, results of operations and cash flows. As of September 28, 2014, the Company held option contracts and forward contracts with an aggregate notional value of zero and $53.2 million, respectively, to hedge balance sheet exposure. The maturity dates of these contracts range from September 2014 to March 2015. The Company held option contracts and forward contracts with an aggregate notional value of $9.4 million and $32.1 million, respectively, as of December 29, 2013, to hedge balance sheet exposure.

Credit Risk

The Company's option and forward contracts do not contain any credit-risk-related contingent features. The Company is exposed to credit losses in the event of nonperformance by the counterparties to these option and forward contracts. The Company enters into derivative contracts with high-quality financial institutions and limits the amount of credit exposure to any single counterparty. In addition, the derivative contracts are limited to a time period of 12 months or less and the Company continuously evaluates the credit standing of its counterparties.

Note 11. INCOME TAXES

In the three and nine months ended September 28, 2014, the Company's income tax benefit of $8.3 million and $2.9 million, respectively, on an income before income taxes and equity in earnings of unconsolidated investees of $7.3 million and $53.2 million, respectively, was primarily due to an increase in forecasted profit before tax for the fiscal period, provision to return adjustments, and acquired deferred tax liabilities used to reduce the valuation allowance, partially offset by state taxes and the recognition of previously unrecognized tax benefits. In the three and nine months ended September 29, 2013, the Company's income tax benefit of $4.6 million and income tax provision of $2.9 million, respectively, on an income before income taxes and equity in earnings of unconsolidated investees of $81.2 million and $30.3 million respectively, was primarily due to projected tax expense in profitable foreign jurisdictions as well as minimum taxes and the recognition of a previously unrecognized tax benefit.

Fair Value Disclosures [Abstract]

Fair Value Disclosures [Text Block]

FAIR VALUE MEASUREMENTS

Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement (observable inputs are the preferred basis of valuation):

• Level 1 — Quoted prices in active markets for identical assets or liabilities.

• Level 2 — Measurements are inputs that are observable for assets or liabilities, either directly or indirectly, other than quoted prices included within Level 1.

• Level 3 — Prices or valuations that require management inputs that are both significant to the fair value measurement and unobservable.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

The Company measures certain assets and liabilities at fair value on a recurring basis. There were no transfers between fair value measurement levels during any presented period. The Company did not have any assets or liabilities measured at fair value on a recurring basis requiring Level 3 inputs as of September 28, 2014 or December 29, 2013.

The following table summarizes the Company's assets and liabilities measured and recorded at fair value on a recurring basis as of September 28, 2014 and December 29, 2013, respectively:

Total liabilities	$	157,319	$	—	$	157,319	$	117,202	$	—	$	117,202

¹  The Company's cash equivalents consist of money market fund instruments and commercial paper that are classified as available-for-sale and are highly liquid investments with original maturities of 90 days or less. The Company's money market fund instruments are categorized within Level 1 of the fair value hierarchy because they are valued using quoted market prices for identical instruments in active markets.

Other financial instruments, including the Company's accounts receivable, accounts payable and accrued liabilities, are carried at cost, which generally approximates fair value due to the short-term nature of these instruments.

Debt Derivatives

The 4.50% Bond Hedge (as defined in Note 9) and the embedded cash conversion option within the 4.50% debentures due 2015 (as defined in Note 9) are classified as derivative instruments that require mark-to-market treatment with changes in fair value reported in the Company's Consolidated Statements of Operations. The fair values of these derivative instruments were determined utilizing the following Level 1 and Level 2 inputs:

	As of 1
	September 28, 2014			December 29, 2013
Stock price	$	36.11		$	28.91
Exercise price	$	22.53		$	22.53
Interest rate	0.29		%	0.33		%
Stock volatility	54.9		%	57.7		%
Credit risk adjustment	0.21		%	0.71		%
Maturity date	February 18, 2015			February 18, 2015

¹  The valuation model utilizes these inputs to value the right but not the obligation to purchase one share of the Company's common stock at $22.53. The Company utilized a Black-Scholes valuation model to value the 4.50% Bond Hedge and embedded cash conversion option. The underlying input assumptions were determined as follows:

(i) Stock price. The closing price of the Company's common stock on the last trading day of the quarter.

(ii) Exercise price. The exercise price of the 4.50% Bond Hedge and the embedded cash conversion option.

(iii) Interest rate. The Treasury Strip rate associated with the life of the 4.50% Bond Hedge and the embedded cash conversion option.

(iv) Stock volatility. The volatility of the Company's common stock over the life of the 4.50% Bond Hedge and the embedded cash conversion option.

(v) Credit risk adjustment. Represents the weighted average of the credit default swap rate of the counterparties.

Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis

The Company measures certain investments and non-financial assets (including project assets, property, plant and equipment, and other intangible assets) at fair value on a non-recurring basis in periods after initial measurement in circumstances when the fair value of such asset is impaired below its recorded cost.

Held-to-Maturity Debt Securities

The Company's debt securities, classified as held-to-maturity, consist of Philippine government bonds that are maintained as collateral for present and future business transactions within the country. These bonds have maturity dates of up to five years and are classified as "Restricted long-term marketable securities" on the Company's Consolidated Balance Sheets. As of September 28, 2014 and December 29, 2013, these bonds had a carrying value of $7.2 million and $8.9 million respectively. The Company records such held-to-maturity investments at amortized cost based on its ability and intent to hold the securities until maturity. The Company monitors for changes in circumstances and events that would affect its ability and intent to hold such securities until the recorded amortized costs are recovered. No other-than-temporary impairment loss was incurred during any presented period. The held-to-maturity debt securities were categorized in Level 2 of the fair value hierarchy.

Equity and Cost Method Investments

The Company holds equity investments in non-consolidated entities that are accounted for under the both equity and cost method. The Company monitors these investments, which are included in "Other long-term assets" in its Consolidated Balance Sheets, for impairment and records reductions in the carrying values when necessary. Circumstances that indicate an other-than-temporary decline include Level 2 and Level 3 measurements such as the valuation ascribed to the issuing company in subsequent financing rounds, decreases in quoted market prices, and declines in operations of the issuer.

As of September 28, 2014 and December 29, 2013, the Company had $137.1 million and $131.7 million, respectively, in investments accounted for under the equity method (see Note 8). As of September 28, 2014 and December 29, 2013, the Company had $17.3 million and $12.4 million, respectively, in investments accounted for under the cost method.

Note 4. LEASING

Residential Lease Program

The Company offers a solar lease program, in partnership with third-party financial institutions, which allows its residential customers to obtain SunPower systems under lease agreements for terms of up to 20 years. Leases are classified as either operating or sales-type leases in accordance with the relevant accounting guidelines.

Operating Leases

The following table summarizes "Solar power systems leased and to be leased, net" under operating leases on the Company's Consolidated Balance Sheets as of September 28, 2014 and December 29, 2013, respectively:

¹  Minimum future rentals on sales-type leases placed in service does not include contingent rentals that may be received from customers under agreements that include performance-based incentives.

Third-Party Financing Arrangements

The Company has entered into multiple facilities under which solar power systems are financed by third-party investors. Under the terms of certain programs the investors make an upfront payment to the Company, which the Company recognizes as a non-recourse liability that will be reduced over the specified term of the program as customer receivables and government incentives are received by the third-party investors. As the non-recourse liability is reduced over time, the Company makes a corresponding reduction in customer and government incentive receivables on its balance sheet. Under this approach, for both operating and sales-type leases the Company continues to account for these arrangements with its residential lease customers in the consolidated financial statements. As of September 28, 2014, and December 29, 2013, the remaining liability to the third-party investors, presented in "Accrued liabilities" and "Other long-term liabilities" on the Company's Consolidated Balance Sheets, was $29.0 million and $46.4 million, respectively (see Note 3).

The Company has entered into a total of seven facilities with third-party investors under which the parties invest in entities that hold SunPower solar power systems and leases with residential customers. The Company holds controlling interests in these less-than-wholly-owned entities and has therefore fully consolidated these entities. The Company accounts for the portion of net assets in the consolidated entities attributable to the investors as "Redeemable noncontrolling interests" and "Noncontrolling interests" in its consolidated financial statements. Noncontrolling interests in subsidiaries that are redeemable at the option of the noncontrolling interest holder are classified as "Redeemable noncontrolling interests in subsidiaries," between liabilities and equity on the Company's Consolidated Balance Sheets. During the three and nine months ended September 28, 2014, the Company received $22.5 million and $75.3 million, respectively, in contributions from investors under the related facilities and attributed $14.7 million and $49.7 million, respectively, in losses to the third-party investors primarily as a result of allocating certain assets, including tax credits, to the investors. By comparison, during the three and nine months ended September 29, 2013, the Company received $29.5 million and $73.4 million, respectively, in contributions from investors under these facilities and attributed $21.0 million and $43.6 million, respectively, in losses to the third-party investors primarily as a result of allocating certain assets, including tax credits, to the investors.

Sale-Leaseback Arrangements

The Company enters into sale-leaseback arrangements under which solar power systems are sold to third parties and subsequently leased back by the Company over minimum lease terms of up to 20 years. Separately, the Company enters into power purchase agreements ("PPAs") with end customers, who host the leased solar power systems and buy the electricity directly from the Company under PPAs with durations of up to 20 years. At the end of the lease term, the Company has the option to purchase the systems at fair value or may be required to remove the systems and return them to the third parties.

The Company has classified its sale-leaseback arrangements of solar power systems not involving integral equipment as operating leases. The deferred profit on the sale of these systems is recognized over the term of the lease. As of September 28, 2014, future minimum lease obligations associated with these systems was $97.5 million, which will be recognized over the minimum lease terms. Future minimum payments to be received from customers under PPAs associated with the solar power systems under sale-leaseback arrangements classified as operating leases will be recognized over the lease terms of up to 20 years and are contingent upon the amounts of energy produced by the solar power systems.

The Company enters into sale-leaseback arrangements under which the systems under the sale-leaseback arrangements have been determined to be integral equipment as defined under the accounting guidance for such transactions. The Company was further determined to have continuing involvement with the solar power systems throughout the lease due to purchase option rights. As a result of such continuing involvement, the Company accounts for each transaction as a financing. Under the financing method, the proceeds received from the sale of the solar power systems are recorded by the Company as financing liabilities and presented within "Other long-term liabilities" in the Company's Consolidated Balance Sheets (see Note 3). The financing liabilities are subsequently reduced by the Company's payments to lease back the solar power systems, less interest expense calculated based on the Company's incremental borrowing rate adjusted to the rate required to prevent negative amortization. The solar power systems under the sale-leaseback arrangements remain on the Company's balance sheet and are classified within "Property, plant and equipment, net" (see Note 3). As of September 28, 2014, future minimum lease obligations for the sale-leaseback arrangements accounted for under the financing method were $80.3 million, which will be recognized over the lease terms of up to 20 years.

Earnings Per Share [Abstract]

Earnings Per Share [Text Block]

NET INCOME PER SHARE

The Company calculates net income per share by dividing earnings allocated to common stockholders by the weighted average number of common shares outstanding for the period.

Diluted weighted average shares is computed using basic weighted average shares plus any potentially dilutive securities outstanding during the period using the treasury-stock-type method and the if-converted method, except when their effect is anti-dilutive. Potentially dilutive securities include stock options, restricted stock units, the Upfront Warrants held by Total, warrants associated with the CSO2015 and CSO2014, and senior convertible debentures.

The following table presents the calculation of basic and diluted net income per share:

The Upfront Warrants allow Total to acquire up to 9,531,677 shares of the Company's common stock at an exercise price of $7.8685. Holders of the Warrants under the CSO2015 and CSO2014, may acquire up to 11.1 million and 8.7 million shares, respectively, of the Company's common stock at an exercise price of $24.00 and $26.40, respectively. If the market price per share of the Company's common stock for the period exceeds the established strike price of the respective warrants, they will have a dilutive effect on its diluted net income per share using the treasury-stock-type method. In February 2014, the CSO2014 was settled, leaving none of the related Warrants outstanding (see Note 9).

Holders of the Company's 0.875% debentures due 2021, 0.75% debentures due 2018, and the 4.75% debentures due 2014 may convert the debentures into shares of the Company's common stock, at the applicable conversion rate, at any time on or prior to maturity. These debentures are included in the calculation of diluted net income per share if they were outstanding during the period presented and if their inclusion is dilutive under the if-converted method. In April 2014, the 4.75% debentures matured and were fully settled in both cash and shares of the Company's common stock during the quarter (see Note 9).

Holders of the Company's 4.50% debentures due 2015 may, under certain circumstances at their option, convert the debentures into cash, and not into shares of the Company's common stock (or any other securities). Therefore, the 4.50% debentures due 2015 are excluded from the net income per share calculation.

The following is a summary of outstanding anti-dilutive potential common stock that was excluded from income per diluted share in the following periods:

Equity Method Investments and Joint Ventures Disclosure [Text Block]

EQUITY METHOD INVESTMENTS

As of September 28, 2014 and December 29, 2013, the Company's carrying value of its equity method investments totaled $137.1 million and $131.7 million, respectively, and is classified as “Other long-term assets” in its Consolidated Balance Sheets. The Company's share of its earnings (loss) from equity method investments is reflected as "Equity in earnings of unconsolidated investees" in its Consolidated Statement of Operations.

Equity Investment and Joint Venture with AUOSP

In fiscal 2010, the Company, AUO and AU Optronics Corporation, the ultimate parent company of AUO ("AUO Taiwan"), formed the joint venture AUOSP. The Company and AUO each own 50% of the joint venture AUOSP. AUOSP owns a solar cell manufacturing facility in Malaysia and manufactures solar cells and sells them on a "cost-plus" basis to the Company and AUO.

In connection with the joint venture agreement, the Company and AUO also entered into licensing and joint development, supply, and other ancillary transaction agreements. Through the licensing agreement, the Company and AUO licensed to AUOSP, on a non-exclusive, royalty-free basis, certain background intellectual property related to solar cell manufacturing (in the case of the Company), and manufacturing processes (in the case of AUO). Under the seven-year supply agreement with AUOSP, renewable by the Company for one-year periods thereafter, the Company is committed to purchase 80% of AUOSP's total annual output allocated on a monthly basis to the Company. The Company and AUO have the right to reallocate supplies from time to time under a written agreement. In fiscal 2010, the Company and AUOSP entered into an agreement under which the Company will resell to AUOSP polysilicon purchased from a third-party supplier and AUOSP will provide prepayments to the Company related to such polysilicon, which prepayment will then be made by the Company to the third-party supplier.

The Company and AUO are not permitted to transfer any of AUOSP's shares held by them, except to each other. In the joint venture agreement, the Company and AUO agreed to each contribute additional amounts through 2014 amounting to $241.0 million, or such lesser amount as the parties may mutually agree. In addition, if AUOSP, the Company or AUO requests additional equity financing to AUOSP, then the Company and AUO will each be required to make additional cash contributions of up to $50.0 million in the aggregate.

The Company has concluded that it is not the primary beneficiary of AUOSP since, although the Company and AUO are both obligated to absorb losses or have the right to receive benefits, the Company alone does not have the power to direct the activities of AUOSP that most significantly impact its economic performance. In making this determination the Company considered the shared power arrangement, including equal board governance for significant decisions, elective appointment, and the fact that both parties contribute to the activities that most significantly impact the joint venture's economic performance. The Company accounts for its investment in AUOSP using the equity method as a result of the shared power arrangement. As of September 28, 2014, the Company's maximum exposure to loss as a result of its equity investment in AUOSP is limited to the carrying value of the investment.

Equity Investment in Huaxia CPV (Inner Mongolia) Power Co., Ltd. ("CCPV")

In December 2012, the Company entered into an agreement with Tianjin Zhonghuan Semiconductor Co. Ltd., Inner Mongolia Power Group Co. Ltd. and Hohhot Jinqiao City Development Company Co., Ltd. to form CCPV, a jointly owned entity to manufacture and deploy the Company's C-7 Tracker concentrator technology in Inner Mongolia and other regions in China. CCPV is based in Hohhot, Inner Mongolia. The establishment of the entity was subject to approval of the Chinese government, which was received in the fourth quarter of fiscal 2013. In December 2013, the Company made a $16.4 million equity investment in CCPV, for a 25% equity ownership.

The Company has concluded that it is not the primary beneficiary of CCPV since, although the Company is obligated to absorb losses and has the right to receive benefits, the Company alone does not have the power to direct the activities of CCPV that most significantly impact its economic performance. The Company accounts for its investment in CCPV using the equity method since the Company is able to exercise significant influence over CCPV due to its board position.

Equity Investment in Diamond Energy Pty Ltd. ("Diamond Energy")

In October 2012, the Company made a $3.0 million equity investment in Diamond Energy, an alternative energy project developer and clean electricity retailer headquartered in Melbourne, Australia, in exchange for a 25% equity ownership.

The Company has concluded that it is not the primary beneficiary of Diamond Energy since, although the Company is obligated to absorb losses and has the right to receive benefits, the Company alone does not have the power to direct the activities of Diamond that most significantly impact its economic performance. The Company accounts for its investment in Diamond using the equity method since the Company is able to exercise significant influence over Diamond due to its board position.

RESTRUCTURING

During fiscal 2012 and 2011, the Company implemented approved restructuring plans, related to all segments, to align with changes in the global solar market, which included the consolidation of the Company's Philippine manufacturing operations as well as actions to accelerate operating cost reduction and improve overall operating efficiency. These restructuring activities were substantially complete as of September 28, 2014. The Company expects to continue to incur costs as it finalizes previous estimates and actions in connection with these plans, primarily due to other costs, such as legal services.

The following table summarizes the restructuring reserve activity during the nine months ended September 28, 2014:

Commitments and Contingencies

Commitments and Contingencies Disclosure [Text Block]

COMMITMENTS AND CONTINGENCIES

Facility and Equipment Lease Commitments

The Company leases certain facilities under non-cancellable operating leases from unaffiliated third parties. As of September 28, 2014, future minimum lease payments for facilities under operating leases was $57.5 million, to be paid over the remaining contractual terms of up to 10 years. The Company also leases certain buildings, machinery and equipment under non-cancellable capital leases. As of September 28, 2014, future minimum lease payments for assets under capital leases was $5.3 million, to be paid over the remaining contractual terms of up to 10 years.

Purchase Commitments

The Company purchases raw materials for inventory and manufacturing equipment from a variety of vendors. During the normal course of business, in order to manage manufacturing lead times and help assure adequate supply, the Company enters into agreements with contract manufacturers and suppliers that either allow them to procure goods and services based on specifications defined by the Company, or that establish parameters defining the Company's requirements. In certain instances, these agreements allow the Company the option to cancel, reschedule or adjust the Company's requirements based on its business needs prior to firm orders being placed. Consequently, only a portion of the Company's disclosed purchase commitments arising from these agreements are firm, non-cancellable, and unconditional commitments.

The Company also has agreements with several suppliers, including some of its non-consolidated investees, for the procurement of polysilicon, ingots, wafers, and Solar Renewable Energy Credits, among others, which specify future quantities and pricing of products to be supplied by the vendors for periods up to 10 years and provide for certain consequences, such as forfeiture of advanced deposits and liquidated damages relating to previous purchases, in the event that the Company terminates the arrangements.

Future purchase obligations under non-cancellable purchase orders and long-term supply agreements as of September 28, 2014 are as follows:

(In thousands)	2014 (remaining three months)		2015	2016	2017	2018	Thereafter	Total1,2
Future purchase obligations	$	557,109	358,634	324,968	292,181	182,517	341,541	$	2,056,950

¹  Total future purchase obligations as of September 28, 2014 include $91.8 million to related parties.

²  Total future purchase obligations was composed of $230.7 million related to non-cancellable purchase orders and $1.8 billion related to long-term supply agreements.

The Company expects that all obligations related to non-cancellable purchase orders for manufacturing equipment will be recovered through future cash flows of the solar cell manufacturing lines and solar panel assembly lines when such long-lived assets are placed in service. Factors considered important that could result in an impairment review include significant under-performance relative to expected historical or projected future operating results, significant changes in the manner of use of acquired assets, and significant negative industry or economic trends. Obligations related to non-cancellable purchase orders for inventories match current and forecasted sales orders that will consume these ordered materials and actual consumption of these ordered materials are compared to expected demand regularly. The Company anticipates total obligations related to long-term supply agreements for inventories will be recovered because quantities are less than management's expected demand for its solar power products. The terms of the long-term supply agreements are reviewed by management and the Company assesses the need for any accruals for estimated losses on adverse purchase commitments, such as lower of cost or market value adjustments that will not be recovered by future sales prices, forfeiture of advanced deposits and liquidated damages, as necessary.

Advances to Suppliers

As noted above, the Company has entered into agreements with various vendors that specify future quantities and pricing of products to be supplied. Certain agreements also provide for penalties or forfeiture of advanced deposits in the event the Company terminates the arrangements. Under certain agreements, the Company is required to make prepayments to the vendors over the terms of the arrangements. During the three and nine months ended September 28, 2014, the Company made additional advance payments totaling $16.4 million and $49.3 million, respectively, in accordance with the terms of existing long-term supply agreements. As of September 28, 2014 and December 29, 2013, advances to suppliers totaled $401.9 million and $383.3 million, respectively, of which $87.8 million and $58.6 million, respectively, is classified as short-term in the Company's Consolidated Balance Sheets. Two suppliers accounted for 82% and 18% of total advances to suppliers as of September 28, 2014, and 77% and 22% as of December 29, 2013. As of September 28, 2014, the Company has remaining future prepayment obligations totaling $16.4 million through the end of fiscal 2014 .

Advances from Customers

The Company has entered into other agreements with customers who have made advance payments for solar power products and systems. These advances will be applied as shipments of product occur or upon completion of certain project milestones. The estimated utilization of advances from customers as of September 28, 2014 is as follows:

(In thousands)	2014 (remaining three months)		2015	2016	2017	2018	Thereafter	Total
Estimated utilization of advances from customers	$	7,020	34,850	22,713	27,039	27,039	72,106	$	190,767

In fiscal 2010, the Company and its joint venture, AUO SunPower Sdn. Bhd. ("AUOSP"), entered into an agreement under which the Company resells to AUOSP polysilicon purchased from a third-party supplier. Advance payments provided by AUOSP related to such polysilicon are then made by the Company to the third-party supplier. These advance payments are applied as a credit against AUOSP’s polysilicon purchases from the Company. Such polysilicon is used by AUOSP to manufacture solar cells which are sold to the Company on a "cost-plus" basis. As of September 28, 2014 and December 29, 2013, outstanding advance payments received from AUOSP totaled $170.8 million and $181.3 million, respectively, of which $17.3 million and $14.0 million, respectively, is classified as short-term in the Company's Consolidated Balance Sheets, based on projected product shipment dates.

Product Warranties

The following table summarizes accrued warranty activity for the three and nine months ended September 28, 2014 and September 29, 2013, respectively:

	Three Months Ended						Nine Months Ended
(In thousands)	September 28, 2014			September 29, 2013			September 28, 2014			September 29, 2013
Balance at the beginning of the period	$	150,793		$	126,293		$	149,372		$	117,172

Settlements made during the period	(5,162		)	(1,161		)	(13,242		)	(4,392		)
Balance at the end of the period	$	154,743		$	134,775		$	154,743		$	134,775

Contingent Obligations

Project agreements often require the Company to undertake obligations including: (i) system output performance guarantees; (ii) system maintenance; (iii) penalty payments or customer termination rights if the system the Company is constructing is not commissioned within specified timeframes or other milestones are not achieved; and (iv) system put-rights whereby the Company could be required to buy back a customer's system at fair value on specified future dates if certain minimum performance thresholds are not met for periods of up to two years. Historically, the Company's systems have performed significantly above the performance guarantee thresholds, and there have been no cases in which the Company has had to buy back a system.

Future Financing Commitments

The Company is required to provide certain funding under the joint venture agreement with AU Optronics Singapore Pte. Ltd. ("AUO") and another unconsolidated investee, subject to certain conditions (see Note 8). As of September 28, 2014, the Company has future financing obligations through 2014 totaling $243.9 million.

Liabilities Associated with Uncertain Tax Positions

Total liabilities associated with uncertain tax positions were $27.1 million and $28.9 million as of September 28, 2014 and December 29, 2013, respectively, and are included in "Other long-term liabilities" in the Company's Consolidated Balance Sheets as they are not expected to be paid within the next 12 months. Due to the complexity and uncertainty associated with its tax positions, the Company cannot make a reasonably reliable estimate of the period in which cash settlement, if any, would be made for its liabilities associated with uncertain tax positions in other long-term liabilities.

Indemnifications

The Company is a party to a variety of agreements under which it may be obligated to indemnify the counterparty with respect to certain matters. Typically, these obligations arise in connection with contracts and license agreements or the sale of assets, under which the Company customarily agrees to hold the other party harmless against losses arising from a breach of warranties, representations and covenants related to such matters as title to assets sold, negligent acts, damage to property, validity of certain intellectual property rights, non-infringement of third-party rights, and certain tax related matters including indemnification to customers under §48(c) solar commercial investment tax credit ("ITC") and Treasury Grant payments under Section 1603 of the American Recovery and Reinvestment Act ("Cash Grant"). In each of these circumstances, payment by the Company is typically subject to the other party making a claim to the Company that is contemplated by and valid under the indemnification provisions of the particular contract, which provisions are typically contract-specific, as well as bringing the claim under the procedures specified in the particular contract. These procedures usually allow the Company to challenge the other party's claims or, in case of breach of intellectual property representations or covenants, to control the defense or settlement of any third party claims brought against the other party. Further, the Company's obligations under these agreements may be limited in terms of activity (typically to replace or correct the products or terminate the agreement with a refund to the other party), duration and/or amounts. In some instances, the Company may have recourse against third parties and/or insurance covering certain payments made by the Company.

In certain limited circumstances the Company has provided indemnification to customers and investors under which the Company is contractually obligated to compensate these parties for losses they may suffer as a result of reductions in benefits received under ITC and Treasury Cash Grant programs. The Company applies for ITC and Cash Grant incentives based on guidance provided by IRS and the Treasury Department, which include assumptions regarding the fair value of the qualified solar power systems, among others.  Certain of the Company’s development agreements, sales-leaseback arrangements, and financing arrangements with investors of its residential lease program, incorporate assumptions regarding the future level of incentives to be received, which in some instances may be claimed directly by its customers and investors. Since the Company cannot determine future revisions to the U.S. Treasury guidelines governing system values or how the IRS will evaluate system values used in claiming ITCs, the Company is unable to reliably estimate the maximum potential future payments that it could have to make under the Company’s contractual investor obligation as of each reporting date.

Legal Matters

Derivative Litigation

Derivative actions purporting to be brought on the Company's behalf have been filed in state and federal courts against several of the Company's current and former officers and directors. The actions arise from the Audit Committee's investigation announcement on November 16, 2009 regarding certain unsubstantiated accounting entries. The California state derivative cases were consolidated as In re SunPower Corp. S'holder Derivative Litig., Lead Case No. 1-09-CV-158522 (Santa Clara Sup. Ct.), and co-lead counsel for plaintiffs have been appointed. The complaints assert state-law claims for breach of fiduciary duty, abuse of control, unjust enrichment, gross mismanagement, and waste of corporate assets. Plaintiffs filed a consolidated amended complaint on March 5, 2012. The federal derivative complaints were consolidated as In re SunPower Corp. S'holder Derivative Litig., Master File No. CV-09-05731-RS (N.D. Cal.), and lead plaintiffs and co-lead counsel were appointed on January 4, 2010. The federal complaints assert state-law claims for breach of fiduciary duty, waste of corporate assets, and unjust enrichment, and seek an unspecified amount of damages. Plaintiffs filed a consolidated complaint on May 13, 2011. A Delaware state derivative case, Brenner v. Albrecht, et al., C.A. No. 6514-VCP (Del Ch.), was filed on May 23, 2011 in the Delaware Court of Chancery. The complaint asserted state-law claims for breach of fiduciary duty and contribution and indemnification, and sought an unspecified amount of damages. On December 19, 2013, the parties executed a stipulated settlement agreement, providing that all claims against all defendants would be released and dismissed with prejudice, and that the Company would not oppose a request by the plaintiffs' counsel for an award of attorneys' fees up to $1 million, one half of which would be paid from the proceeds of directors and officers liability insurance. At a hearing on August 22, 2014, the Superior Court of California for Santa Clara County entered an order providing for final approval of the stipulated settlement and dismissing that action with prejudice. On September 9, 2014, the court in the consolidated federal derivative action dismissed that action with prejudice. Those dismissals are now final. On October 22, 2014, the Delaware Chancery Court entered an order dismissing the Delaware derivative action with prejudice.

Tax Benefit Indemnification Litigation

On March 19, 2014, the Company received notice that a lawsuit had been filed by NRG Solar LLC (“NRG”) against SunPower Corporation, Systems, a wholly-owned subsidiary of the Company (“SunPower Systems”), in the Superior Court of Contra Costa County, California.  The complaint asserts that, according to the indemnification provisions in the contract pertaining to SunPower Systems’ sale of a large California solar project to NRG, SunPower Systems owes NRG $75 million in connection with certain tax benefits associated with the project that were approved by the Treasury Department for an amount that was less than expected. The Company does not believe that the facts support NRG’s claim under the operative indemnification provisions and intends to vigorously contest the claim. On May 5, 2014, SunPower Systems filed a demurrer to NRG’s complaint, which remains pending. The Court sustained the demurrer with leave to amend. NRG filed its amended complaint on September 3, 2014. The Company filed a demurrer to NRG's amended complaint on September 22, 2014, and that demurrer is scheduled to be heard on November 18, 2014. The Court has not yet set a trial date or case schedule. The company is currently unable to determine if the resolution of this matter will have an adverse effect on the company's financial position, liquidity or results of operations. 

Other Litigation

The Company is also a party to various other litigation matters and claims that arise from time to time in the ordinary course of its business. While the Company believes that the ultimate outcome of such matters will not have a material adverse effect on the Company, their outcomes are not determinable and negative outcomes may adversely affect the Company's financial position, liquidity or results of operations.

¹  The fair value of the convertible debt was determined using Level 1 inputs based on quarterly market prices as reported by an independent pricing source.

The Company's outstanding convertible debentures are senior, unsecured obligations of the Company, ranking equally with all existing and future senior unsecured indebtedness of the Company.

0.875% Debentures Due 2021

In June 2014, the Company issued $400.0 million in principal amount of its 0.875% debentures due 2021. Interest is payable semi-annually, beginning on December 1, 2014. Holders may exercise their right to convert the debentures at any time into shares of the Company's common stock at an initial conversion price approximately equal to $48.76 per share, subject to adjustment in certain circumstances. If not earlier repurchased or converted, the 0.875% debentures due 2021 mature on June 1, 2021.

0.75% Debentures Due 2018

In May 2013, the Company issued $300.0 million in principal amount of its 0.75% debentures due 2018. Interest is payable semi-annually, beginning on December 1, 2013. Holders may exercise their right to convert the debentures at any time into shares of the Company's common stock at an initial conversion price approximately equal to $24.95 per share, subject to adjustment in certain circumstances. If not earlier repurchased or converted, the 0.75% debentures due 2018 mature on June 1, 2018.

4.50% Debentures Due 2015

In 2010, the Company issued $250.0 million in principal amount of its 4.50% senior cash convertible debentures ("4.50% debentures due 2015"). Interest is payable semi-annually, beginning on September 15, 2010. If not earlier repurchased or converted, the 4.50% debentures due 2015 mature on March 15, 2015. The 4.50% debentures due 2015 are convertible, upon certain events and restrictions, only into cash, and not into shares of the Company's common stock (or any other securities) at an initial conversion price of $22.53 per share. The conversion price is subject to adjustment in certain events, such as distributions of dividends or stock splits. Upon conversion, the Company will deliver cash in an amount calculated by reference to the price of its common stock over the applicable observation period.

The embedded cash conversion option is a derivative instrument (derivative liability) that is required to be separated from the 4.50% debentures due 2015. The fair value of the derivative liability is classified within "Other long-term liabilities" on the Company's Consolidated Balance Sheets. Changes in the fair value of the derivative liability are reported in the Company's Consolidated Statements of Operations until such transaction settles or expires.

During the three and nine months ended September 28, 2014, the Company recognized a non-cash gain of $56.7 million and non-cash loss of $44.6 million, respectively, recorded in "Other, net" in the Company's Consolidated Statement of Operations related to the change in fair value of the embedded cash conversion option. During the three and nine months ended September 29, 2013 the Company recognized a non-cash loss of $36.0 million and $94.3 million, respectively, recorded in "Other, net" in the Company's Consolidated Statement of Operations related to the change in fair value of the embedded cash conversion option.

Call Spread Overlay with Respect to 4.50% Debentures

Concurrently with the issuance of the 4.50% debentures due 2015, the Company entered into privately-negotiated convertible debenture hedge transactions (collectively, the "4.50% Bond Hedge") and warrant transactions (collectively, the "4.50% Warrants" and together with the 4.50% Bond Hedge, the “CSO2015”), with certain of the initial purchasers of the 4.50% debentures due 2015 or their affiliates. The CSO2015 transactions represent a call spread overlay with respect to the 4.50% debentures due 2015, whereby the cost of the 4.50% Bond Hedge purchased by the Company to cover the cash outlay upon conversion of the debentures is reduced by the sales prices of the 4.50% Warrants. Assuming full performance by the counterparties (and 4.50% Warrants strike prices above the conversion price of the 4.50% debentures due 2015), the transactions effectively reduce the Company's potential payout over the principal amount on the 4.50% debentures due 2015 upon conversion of the 4.50% debentures due 2015.

Under the terms of the 4.50% Bond Hedge, the Company bought options to acquire, at an exercise price of $22.53 per share, subject to customary adjustments for anti-dilution and other events, cash in an amount equal to the market value of up to 11.1 million shares of the Company's common stock. Under the terms of the 4.50% Warrants the Company sold warrants to acquire, at an exercise price of $24.00 per share, up to 11.1 million shares of the Company's common stock. Each 4.50% Bond Hedge and 4.50% Warrant transaction is a separate transaction, entered into by the Company with each counterparty, and is not part of the terms of the 4.50% debentures due 2015.

The 4.50% Bond Hedge, which is indexed to the Company's common stock, is a derivative instrument that requires mark-to-market accounting treatment due to the cash settlement features until such transactions settle or expire. The fair value of the 4.50% Bond Hedge is classified as "Other long-term assets" in the Company's Consolidated Balance Sheets.

During the three and nine months ended September 28, 2014, the Company recognized a non-cash loss of $56.7 million and non-cash gain of $44.6 million, respectively, in "Other, net" in the Company's Consolidated Statement of Operations related to the change in fair value of the 4.50% Bond Hedge. During the three and nine months ended September 29, 2013, the Company recognized a non-cash gain of $36.0 million and $94.3 million, respectively, in "Other, net" in the Company's Consolidated Statement of Operations related to the change in fair value of the 4.50% Bond Hedge.

4.75% Debentures Due 2014

In May 2009, the Company issued $230.0 million in principal amount of its 4.75% senior convertible debentures ("4.75% debentures due 2014"). Interest on the 4.75% debentures due 2014 was payable semi-annually, beginning October 15, 2009. Holders of the 4.75% debentures due 2014 were able to exercise their right to convert the debentures at any time into shares of the Company's common stock at a conversion price equal to $26.40 per share, subject to adjustment upon certain events. In April 2014, the 4.75% debentures due 2014 matured. During April 2014, the Company issued approximately 7.1 million shares of its common stock to holders that exercised conversion rights prior to their maturity and paid holders an aggregate of $41.7 million in cash in connection with the settlement of the remaining 4.75% debentures. Subsequent to the maturity date, no 4.75% debentures remained outstanding.

Call Spread Overlay with Respect to the 4.75% Debentures

Concurrently with the issuance of the 4.75% debentures due 2014, the Company entered into certain convertible debenture hedge transactions (the "4.75% Bond Hedge") and warrant transactions (the "4.75% Warrants") with affiliates of certain of the underwriters of the 4.75% debentures due 2014 (together, the "CSO2014"), whereby the cost of the 4.75% Bond Hedges purchased by the Company to cover the potential share outlays upon conversion of the debentures was reduced by the sales prices of the 4.75% Warrants. The CSO2014 were not subject to mark-to-market accounting treatment since they could only be settled by issuance of the Company's common stock.

The 4.75% Bond Hedge allowed the Company to purchase up to 8.7 million shares of the Company's common stock, on a net share basis. Each 4.75% Bond Hedge and 4.75% Warrant was a separate transaction, entered into by the Company with each counterparty, and was not part of the terms of the 4.75% debentures due 2014. The exercise prices of the 4.75% Bond Hedge were $26.40 per share of the Company's common stock, subject to customary adjustment for anti-dilution and other events. In February 2014, the parties agreed to unwind the 4.75% Bond Hedge in full for a total cash settlement of $68.8 million, calculated by reference to the weighted price of the Company's common stock on the settlement day, received by the Company.

Under the 4.75% Warrants, the Company sold warrants to acquire up to 8.7 million shares of the Company's common stock at an exercise price of $26.40 per share of the Company's common stock, subject to adjustment for certain anti-dilution and other events. In February 2014, the parties agreed to unwind the 4.75% Warrants in full for a total cash settlement of $81.1 million, calculated by reference to the weighted price of the Company's common stock on the settlement date, paid by the Company.

Other Debt and Credit Sources

Mortgage Loan Agreement with IFC

In May 2010, the Company entered into a mortgage loan agreement with IFC. Under the loan agreement, we borrowed $75.0 million and are required to repay the amount borrowed starting two years after the date of borrowing, in 10 equal semi-annual installments. The Company is required to pay interest of LIBOR plus 3% per annum on outstanding borrowings; a front-end fee of 1% on the principal amount of borrowings at the time of borrowing; and a commitment fee of 0.5% per annum on funds available for borrowing and not borrowed. The Company may prepay all or a part of the outstanding principal, subject to a 1% prepayment premium. The Company has pledged certain assets as collateral supporting its repayment obligations (see Note 3). As of both September 28, 2014 and December 29, 2013, the Company had restricted cash and cash equivalents of $9.2 million related to the IFC debt service reserve, which is the amount, as determined by IFC, equal to the aggregate principal and interest due on the next succeeding interest payment date.

Loan Agreement with California Enterprise Development Authority ("CEDA")

In 2010, the Company borrowed the proceeds of the $30.0 million aggregate principal amount of CEDA's tax-exempt Recovery Zone Facility Revenue Bonds (SunPower Corporation - Headquarters Project) Series 2010 (the "Bonds") maturing April 1, 2031 under a loan agreement with CEDA. The Bonds mature on April 1, 2031, bear interest at a fixed rate of 8.50% through maturity, and include customary covenants and other restrictions on the Company.

July 2013 Revolving Credit Facility with Credit Agricole

In July 2013, the Company entered into a revolving credit facility with Credit Agricole, as administrative agent, and certain financial institutions, under which the Company may borrow up to $250.0 million. On August 26, 2014, the Company entered into an amendment to the revolving credit facility that, among other things, extends the maturity date of the facility from July 3, 2016 to August 26, 2019 (the "Maturity Date"). Amounts borrowed may be repaid and reborrowed until the Maturity Date. The Company may request increases to the available capacity of the revolving credit facility to an aggregate of $300.0 million, subject to the satisfaction of certain conditions. The revolving credit facility includes representations, covenants, and events of default customary for financing transactions of this type.

The revolving credit facility was entered into in conjunction with the delivery by Total S.A. of a guarantee of the Company's obligations under the related facility. On January 31, 2014, as contemplated by the facility, (i) the Company's obligations under the facility became secured by a pledge of certain accounts receivable and inventory; (ii) certain of the Company's subsidiaries entered into guarantees of the facility; and (iii) Total S.A.'s guarantee of the Company's obligations under the facility expired. Until the expiration of the guarantee on January 31, 2014, the Company was required to pay Total S.A. an annual guarantee fee of 2.75% of the outstanding amount under the revolving credit facility.

Before January 31, 2014, the Company was required to pay interest on outstanding borrowings and fees of (a) with respect to any LIBOR rate loan, 0.60% plus the LIBOR rate divided by a percentage equal to one minus the stated maximum rate of all reserves required to be maintained against "Eurocurrency liabilities" as specified in Regulation D; (b) with respect to any alternative base rate loan, 0.25% plus the greater of (1) the prime rate, (2) the Federal funds rate plus 0.50%, and (3) the one month LIBOR rate plus 1%; and (c) a commitment fee of 0.06% per annum on funds available for borrowing and not borrowed.

After January 31, 2014, the Company is required to pay interest on outstanding borrowings and fees of (a) with respect to any LIBOR rate loan, an amount ranging from 1.50% to 2.00% (depending on the Company's leverage ratio from time to time) plus the LIBOR rate divided by a percentage equal to one minus the stated maximum rate of all reserves required to be maintained against “Eurocurrency liabilities” as specified in Regulation D; (b) with respect to any alternate base rate loan, an amount ranging from 0.50% to 1.00% (depending on the Company's leverage ratio from time to time) plus the greater of (1) the prime rate, (2) the Federal Funds rate plus 0.50%, and (3) the one-month LIBOR rate plus 1%; and (c) a commitment fee ranging from 0.25% to 0.35% (depending on the Company's leverage ratio from time to time) per annum on funds available for borrowing and not borrowed.

As of September 28, 2014 and December 29, 2013, the Company had no outstanding borrowings under the revolving credit facility.

Liquidity Support Agreement with Total S.A.

In February 2012, the Company entered into a Liquidity Support Agreement with Total S.A. and the DOE, and a series of related agreements with Total S.A. and Total, under which Total S.A. agreed to provide the Company, or cause to be provided, additional liquidity under certain circumstances. The Liquidity Support Agreement was terminated in the first quarter of fiscal 2014. There were no outstanding guarantees or debt under the agreement upon termination (see Note 2).

Project Financing

In order to facilitate the construction and sale of certain solar projects, the Company obtains non-recourse project loans from third-party financial institutions that are contemplated as part of the structure of the sales transaction. The customer, which is not a related party to either the financial institution or the Company, in certain circumstances is permitted to assume the loans at the time that the project entity is sold to the customer. During fiscal 2013, the Company entered into a project loan with a consortium of lenders to facilitate the development of a 10 MW utility and power plant projects under construction in Israel. During the first quarter of fiscal 2014, the Company sold the Israeli project. The related loan, amounting to ILS 141.8 million (approximately $40.7 million based on the exchange rate at the time of sale), and accrued and unpaid interest was assumed by the customer. In instances where the debt is issued as a form of pre-established customer financing, subsequent debt assumption is reflected as a financing outflow and operating inflow for purposes of the statement of cash flows to reflect the substance of the assumption as a facilitation of customer financing from a third-party.

Other Debt

During fiscal 2014, the Company entered into two long-term non-recourse loans to finance solar power systems and leases under its residential lease program. In fiscal 2014 the Company drew down $74.8 million of proceeds, net of issuance costs, under the loan agreements.

During fiscal 2013, the Company entered into a long-term non-recourse loan agreement with a third-party financial institution to finance a 5.4 MW utility and power plant operating in Arizona. The outstanding balance of the loan as of September 28, 2014 was $8.7 million.

Other debt is further composed of non-recourse project loans in EMEA which are scheduled to mature through 2028.

August 2011 Letter of Credit Facility with Deutsche Bank

In August 2011, the Company entered into a letter of credit facility agreement with Deutsche Bank, as administrative agent, and certain financial institutions. Payment of obligations under the letter of credit facility is guaranteed by Total S.A. pursuant to the Credit Support Agreement (see Note 2). The letter of credit facility provides for the issuance, upon request by the Company, of letters of credit by the issuing banks thereunder in order to support certain obligations of the Company, in an aggregate amount not to exceed $878.0 million for the period from January 1, 2014 through December 31, 2014. Aggregate letter of credit amounts may be increased upon the agreement of the parties but, otherwise, may not exceed (i) $936.0 million for the period from January 1, 2015 through December 31, 2015, and (ii) $1.0 billion for the period from January 1, 2016 through June 28, 2016.

As of September 28, 2014 and December 29, 2013, letters of credit issued and outstanding under the August 2011 letter of credit facility with Deutsche Bank totaled $730.0 million and $736.0 million, respectively.

September 2011 Letter of Credit Facility with Deutsche Bank Trust

In September 2011, the Company entered into a letter of credit facility with Deutsche Bank Trust which provides for the issuance, upon request by the Company, of letters of credit to support obligations of the Company in an aggregate amount not to exceed $200.0 million. Each letter of credit issued under the facility is fully cash-collateralized and the Company has entered into a security agreement with Deutsche Bank Trust, granting them a security interest in a cash collateral account established for this purpose.

As of September 28, 2014 and December 29, 2013, letters of credit issued and outstanding under the Deutsche Bank Trust facility amounted to $1.2 million and $2.4 million, respectively, which were fully collateralized with restricted cash on the Consolidated Balance Sheets.

SEGMENT INFORMATION

The Company's President and Chief Executive Officer, as the chief operating decision maker ("CODM"), has organized the Company, manages resource allocations and measures performance of the Company's activities among three regional segments: (i) the Americas Segment, (ii) the EMEA Segment, and (iii) the APAC Segment. The Americas Segment includes both North and South America. The EMEA Segment includes European countries, as well as the Middle East and Africa. The APAC segment includes all Asia-Pacific countries.

The CODM assesses the performance of the three regional segments using information about their revenue and gross margin after certain adjustments to reflect the substance of the revenue transactions for certain utility and power plant projects, and adding back certain non-cash expenses such as stock-based compensation expense and interest expense, as well as other items including gain on contract termination, loss on change in European government incentives, accelerated depreciation associated with the Company's manufacturing step reduction program, and amortization of other intangible assets. The CODM does not review asset information by segment.

The following tables present information by region; including revenue, gross margin, and depreciation and amortization.

¹  The Company's cash equivalents consist of money market fund instruments and commercial paper that are classified as available-for-sale and are highly liquid investments with original maturities of 90 days or less. The Company's money market fund instruments are categorized within Level 1 of the fair value hierarchy because they are valued using quoted market prices for identical instruments in active markets.

Other financial instruments, including the Company's accounts receivable, accounts payable and accrued liabilities, are carried at cost, which generally approximates fair value due to the short-term nature of these instruments.

Fair Value, Measurement Inputs, Disclosure [Text Block]

The fair values of these derivative instruments were determined utilizing the following Level 1 and Level 2 inputs:

	As of 1
	September 28, 2014			December 29, 2013
Stock price	$	36.11		$	28.91
Exercise price	$	22.53		$	22.53
Interest rate	0.29		%	0.33		%
Stock volatility	54.9		%	57.7		%
Credit risk adjustment	0.21		%	0.71		%
Maturity date	February 18, 2015			February 18, 2015

¹  The valuation model utilizes these inputs to value the right but not the obligation to purchase one share of the Company's common stock at $22.53. The Company utilized a Black-Scholes valuation model to value the 4.50% Bond Hedge and embedded cash conversion option. The underlying input assumptions were determined as follows:

(i) Stock price. The closing price of the Company's common stock on the last trading day of the quarter.

(ii) Exercise price. The exercise price of the 4.50% Bond Hedge and the embedded cash conversion option.

(iii) Interest rate. The Treasury Strip rate associated with the life of the 4.50% Bond Hedge and the embedded cash conversion option.

(iv) Stock volatility. The volatility of the Company's common stock over the life of the 4.50% Bond Hedge and the embedded cash conversion option.

(v) Credit risk adjustment. Represents the weighted average of the credit default swap rate of the counterparties.
